I had been riding Compasses for quite some time. I had about 2k miles on my Barlow Passes (pre-tubeless flavor) and replaced them with Snoqualmie passes in order to take advantage of my tubeless rims and whatnots.
That's where my problems began. I've gone through 4 Snoqualmies. About 100 miles in, one got a small cut from a small piece of glass and the sealant wouldn't close it. I bought a new one. The back tire developed a bulge at about 250 miles and was warrantied, which took about a week and a half. One blows off the rim before the bead sets so it has to be run with a tube. I learned that the hard way. My right ear was right next to it and I suffered hearing loss from their bad quality control. So half of the tires were defective, one wasn't very good, and one was fine. None measured out to the claimed 44mm unless I put them on a 26mm internal width Blunt SS rim.
Anyway, when Soma announced their 48c Supple Vitesses I was stoked. I rode their previous 42c version, but since the black tread to skinwall ratio was off I got rid of them (I have mild OCD). The bead on the new SVs are officially tubeless. They're much tighter than Compasses (which you can take on and off with fingers) and sealed up instantly, even on the rim that the Compasses blew off of. Ride quality is probably better than Snoqualmies too. Snoqualmies tend to grip and wrap around everything, including uneven pavement, which makes the bike handle funny under load. SVs have a slightly stiffer sidewall so that doesn't happen.
Anyway, the tl;dr version-
PROS-
Wide (49c on 22mm internal rims)
Cheaper (by 9 bucks)
Handle more predictably
Tubeless ready for real this time
No trips to Urgent Care after setting them up tubeless
Came in under weight (358, 359 vs 370 claimed)
Like 650b road plus, but for tall people
CONS-
Sticky rubber tends to kick up sand at first until it gets a coating of dust on it
Still slightly too much gumwall, but not quite as bad
