I've had similarly disappointing wear on S-Ones. They're great in terms of grip, roll resistance & punctures, but they wear quickly. Not a good commuting tyre !
I'm surprised at the range of experiences you lot have had with tubeless. I've been using tubeless for 2 years, and have had punctures that took a while to seal, but found that they would seal if I rotated the wheel so that the puncture was at the bottom and I pressed a finger against it to slow the loss of air. Slits in the side wall are another story. I carry tubes and a boot in case of those.
When I switched to Conti 4 Seasons for a winter because I felt more confident in their tread, I kept getting punctures. Schwalbe Marathons weigh a ton, but haven't punctured. I use them for commuting in winter now, although they also feel like wagon wheels and have much less grip.
What sealant, rims and tyres (pressure) you use clearly make a huge difference - as does tyre pressure and overall weight. So here's a round up of my set up.
Tyres - Schwalbe S-One (30mm) (started with the first 28mm Schwalbe One tubeless, which were also fine)
Pressures - 70psi front, 80psi rear
Rims - Stan's A400 (disc brakes)
Sealant - Stan's Race Sealant (more, bigger particles)
My Weight - 62kg
Bike - 10kg
All my crap - depends on the ride, but 5-ish kg (?)
