Bench tests show that tubeless is marginally (1-2W) lower than a latex tube for RR which is marginally lower (1-2W) than a butyl tube. It's not marketing, it's scientific. It's not enough to matter for a ride to the grocery or a morning commute, but it starts to add up as the rides get longer, especially into the all and multi day epic sorts of things I do. I mentioned bench tests because they are reliably comparable to each other. As for fiddly? Yes, some tires can be, but most are not, especially if one knows how to mount them and set them up. It's not hard to learn how to do this.
