Vittoria Open Corsa Evo CX. With latex tubes, these are about as close as you can get to tubular. More expensive, but wear quicker and are pretty easy to puncture.
I'm sure there are others. The 4000's are a resonable balance of price, performance, wear and puncture resistance.

I just completed my 1st week on a set of wire bead GatorSkins. Can't complain, but can't recommend just yet either. Time will tell. I will recommend, however, you get the following if you have difficulty mounting this tire:
Crank Brothers Telescoping Speed Tire Lever
It will be the best $4 - $8 you ever spent!

These tires interest me. I'm still running the stock Schwalbe Lugano tires that came with my bike, but when it's time to replace them, I'm considering these GP 4000s. Will I notice an immediate difference (oh wow!), or is it more of a durability thing that I'll notice over time?
However, if the tires proved anything this last weekend it's definitely durability. Was riding with two other friends, not sure what tires they had (women's '10 Synapse and an '11 Allez both stock) but I was in the middle behind the Synapse with my friend on his Specialized at my back. We were essentially drafting each other the entire ride. Single file. Once I got home my friend called to say both her front tire and his rear were completely flat once they got home. None of us could recall what road hazard we had all come across, but my tires powered through and my only guess was that this was a true testament to their durability. I'm glad I made the switch when I did and will likely be a return customer.

I haven't heard about sudden sidewall failures but I've been away from the company for 3 years now. Sorry I can't help here.

I've had two sudden losses of pressure on GP4000s. One was a sidewall blowout - I assume there must have been debris but I never found anything that would have caused the cut. The other was the bead simply lifting off the rim (DA 7900 CLs) for no apparent reason. Both on the rear while riding in a straight line fortunately. I don't like how easy they are to slip on the wheel - easy on has to be easy off, right?
Shame, because they are a great tyre, ride almost as good as Michelin PR3s and have a lot less punctures. But I am starting to lose a bit of confidence in them.

Holy crap, you aren't kidding. I just changed out my gatorskins for Conti Grand Prix's when I got my new wheels. I almost bent a tire lever trying to get them on the new wheels before I decided to buy new. The Grand Prix's went on by hand. I guess the good news is I never flatted on the gators over a couple thousand miles.

I switched to the GP4000S and they feel a lot better on turns than my old tires, which were whatever comes on a CAAD 10-4.
Apart from the turns I didn't notice any difference, but I'm hoping to reduce my flat count, which is at 3 in 500 miles for the old tires.

I have heard and read that the color versions are silica and not black chili. Assuming this I would guess that grip and rolling resistance would be affected. I have also been told by LBS that the color versions wear faster.

At LEAST 25's... At 280 + 20 lb for the bike, 60% on the rear wheel, you're looking at 180 lb on the rear wheel. According to this chart, even 28's are on the small side for that application at 120 PSI: https://www.bikequarterly.com/images/TireDrop.pdf
Your rims were probably rubbing against your sidewalls often with 23's. With 120 lb on the front wheel, 23's or 25's are not so bad up there....25's at 110 PSI would probably be good for the front, according to that chart anyway.

Completely different tyres that can't be compared, clear description of the two on Continentals website.

My most recent GP4000 (Black with reflex side) was the exact opposite....a complete PITA to get onto my rim (Ritchey). I'm not looking forward to having to fix a flat out on a 100 degree day. But I love the tires.
Wiggle has them for $42 right now.

Alternatively probikekit has the 4000S branded ones for $47 with a Continental Race Lite tube (currently $9.41 ea) and free shipping. Add coupon code VELONEWS10 to take 10% off of that = $84.67 shipped for a pair of the flashy ones plus a pair of tubes

This is my third summer riding 4000/4000S. They're nice tires. I've ridden Vittorias, Panaracers, Specialized (I don't know actual mfr for these) and others. I'm not a fanatic for any specific brand. I like Schwalbe Dureme 32's for winter riding (lots of nasty silica spicules in winter-road sanding, Duremes repel them).
With 4000, I've had one pinch flat riding 23s on really radical rumble strip, a puncture flat trying to ride with no wear-dimple left ca. 2700 mi, I changed to 25s, had a sidewall blow-out ( front) at 1400 mi, rear 25mm is doing fine at ca. 3000 mi. For the front, Iwent back to 23. I carry a spare 23, 4000S foldable, in my saddlebag. Plus two tubes.
In the semi-old days, I used to just carry a patch kit, instead of spare tubes. It worked fine.
