My quest for comfort is finally over, or is it?
I have a Jamis Renegade Exploit bike and from the begining I was trying to make this bike as comfortable as possible. The frame was a good starting point because it is steel and offers a lot of nice flex. But I wanted more so I started with swappping a seatpost for VLCS 2.0 made by Ergon. A lot of improvement but still I wanted more. So I changed tires for bigger ones (Panaracer GravelKing SK 43mm - but not tubeless and with narrow rim they measure just 41 mm). Then I wanted to get even more comfort so I bought Redshift Shockstop stem. After experimenting with elasotmers I settled for the most supple combination dedicated for drop handlebar and it works really nice. For the comfort of my butt I bought a Brooks C17 saddle (very good purchase indeed!) and to get more upright position I swapped the Rithey evomax comp handlebar for Specialized hoover bar with 15 mm rise and 12 flare and used Supacaz Super Sticky Kush bar tape. Another great addition but I also needed better gearing for going uphill so I changled rear cassette for Shimano 11-40 and rear derailleur for new Shimano 105 R7000. With longer chain it works very nice. For my weak knee I also bought a Speedplay Frog cleats. Now the last thing I was considering was going for even more wide tires but this could cause a lot of problems (toe overlap, changing the front derailleur for new Shimano 105 7000 to get more space in the back and a potential problems with too narrow rim - 17 mm wide) so I decided not to. But maybe there are better (more supple) tires in 42mm size out there because I feel that, although very durable and safe, the Panaracer Gravelking SK are not the most comfortable tires on the market. What do you think?

You're doing it wrong.
But on a serious note, you're doing it wrong. The vast majority of a bikes "suppleness" is derived from the tires. You should have stuck with your 43mm GKs and set them up tubeless. Tubeless is the key here, it makes such a huge difference it's not even funny. It's a plenty supple tire but if you're looking for even more supple (and less durable) then there are other options, like Compass tires.

Get some ti spindles for the Frogs.
I picked up a cheap used set of ti Frogs and switched out the steel axle on my pair.
It genuinely felt as is the 'hits' through the pedal were duller/softer a bit.
Or maybe its just in my head !

And do you belive that tubeless tire is more supple than tubed with the same pressure?
I think this is a personal matter. If you start with a small frame and low stack (like me) you can gain more comfort by rising the handlebar. For me this was chagne for the better not worse.

true, I guess I should have said comfort for me starts at having the hoods = to saddle height or lower than

Absolutely. Tubeless > tubed, in every situation, way, shape, and form.

I’m going tubeless on my gravel bike in a couple months, when I swap tires, so I’m planning to put this to the test!
On my mountain bike, riding technical single track, it’s a game changer for sure. But on my gravel bike and the relatively tame gravel I ride, I’m not as sold. I have 650x47 GKSK and with pressure at 30 or a tad lower (25mm KOM internal width) I’ve always found them supple. So I figured why bother. But I want to try it just in case!

Tubless lets you run low pressure without getting a pinch flat, and of course helps seal reasonable size punctures.
It does't make the bike ride more comfortable at the same PSI. Its great if you only have one bike and don't mind the maintenance, but its not a requirement. Its biggest benefit for me was preventing pinch flats on gravel or rough terrain, while letting me run lower pressures.

Well . . . it's an overgeneralization to say that tubeless is ALWAYS superior. It depends on the tire. Not all tires are created equal and sometimes tubeless-ready tires are much heavier and stiffer than their tubed equivalents. I've ridden Challenge tires since before most people knew gravel was a thing -- I'm a fan. But Challenge's Gravel Grinder tubeless tires tend to be pretty stiff and harsh compared to their tubed versions. (For that reason, I'm changing to Challenge's Strada Bianca tubeless for road/upscale gravel and to WTB 650b's and Panaracer 700c's for tubeless on fun gravel.)

To explore the topic more I starder a comfort challenge project (the address is: gravelbikes.cc) where I want to test all the possible solutions for improving riding comfort. Right now apart from flexing seatpost from Ergon and shockstop stem I managed to test 700x50c tires and measured the difference between tubed and tubeless tires. But I want to do much more test in the future. If you have any suggestions what exactly should I test please tell me. Thank you!
My tests shows that tubeless setup is not necessary ALWAYS superior - not if we look on damping properties

Just a thought, but maybe some of riders need a different geometry + jones bars + 27.5+ tires? maybe even suspension.
truth be told I can't run a jack hammer like I did when I was in my 20's, I also can't run an earth compactor like I did in my 20's. but I have been out of that industry for 30 years, I am not near as strong as I was then.
Maybe the quest for "bicycle comfort" starts with core and strength training? tighten up and condense the mass.

Tire swaps. Just popping on a different set of tires to try out is a quick job with tubes that becomes work with tubeless. Honestly, I rarely got flats with tubes. I've probably spent more time faffing with tubeless sealant and getting tires seated than I ever have spent on the side of the road fixing a flat.

All, keep in mind that when the OP speaks of comfort, he is talking about measurements taken with an iPhone app which measures vibration.
With this app he has determined that tubed tires are more comfortable than tubeless.

If we are to measure "Vibration"...... at what frequency is that Phone app measuring at?

from my measurements (at least for 700c 43 and 50mm Gravelkings) going tubeless is in most cases not beneficial in terms of comfort. But ability to safely ride on tire with 20 psi is a huge bonus of using a tubeless setup. Yet at 30 psi there should be no difference, especially with a wide 47 mm tire in my opinion - but I do too want to test it and will test it soon to be 100% sure

Not an Iphone, an android one And do you asking about frequency of each measurement? I don't have an exact data but it measures changes many times per second and it measures vibrations constantly even for a longer periods of time (much more than I need to run my test route). So it is enough for my purposes.

Having been an app developer I can't imagine using a phone to measure something as small as vibrations. There's just no way that can be accurate.
