Having now tried these back to back vs. Turbo Cottons, TCs TCs TCs.
As far as what goes?
Specialized also has a tubeless version coming out at some point (project black).

Im giving a pair of 28c rubino tlr a hoon for this winter. So far they seem nice. Noticeably slower but i haven't really pushed them round corners and have done no racing recently. Don't hold air as well as the gp5ks i had on previously, i need to pump them up before every ride.
Unlike the corsas i tried earlier this year i was able to bead up with a track pump relatively easily.
They ended up being 50g lighter for a pair of 28c training tyres than the 25c gp5k.

After yesterdays ride, I shall be putting my Corsa 2.0 TLRs back on after next weekends road bike TT.
They have so much more grip than the GP5K TLs. They brake in half the distnce and give me much more confidence when pushing the bike hard in corners.
Had a 'moment' at 85kph round a bend on the Conti's that I know the Corsa's would have handled.

I find the Rubino Pro TLR 28c with Orange Seal holding air ok on SES 4.5 AR after it gone through a few hundred km.
How much do you need to top up every ride? I just need maybe a few pumps every few days.
Couldn't try the GP5K TL to compare for the obvious reason. Would love to try the Corsa TLR but I think the Rubino is gonna last for a long while...

Not sure if this plays a role on the blow out but the beads on the Vittoria look like they are sewn (like non-tubeless tires) and mine have imperfections (and one was leaking out of the box) so I am not going to use high pressures with those tires. Compared to Hutchinson and other tires that look seamless/one piece as below:

@jlok the first couple of days it was drastic. 40psi in front, 25 in rear (down from 80psi).
Just pumped them up after 24hrs and the rear was down 25psi, front only 5.
Im beginning to think i might need to retape the rear rim though. I remember seeing some sealant seeping under the end of the tape. I wonder if that could be giving me grief?

You shouldn’t be losing more than 2-3psi in a day. Run soapy water around the bead/rim interface and check for bubbles. Also put soapy water over you valve stem/core...entirely possible the core is leaking.
Try adding a little more sealant if you are getting leaks through the bead/rim interface.

For the avoidance of doubt, my comments relate to running clinchers latex (vittoria). TCs feel faster, feel softer, and don't sound like I'm riding of a rumble strip at cruising speed.

Vittoria Graphene 2.0 vs Specialized S-works turbo ?
Tc pro: lighter, faster, quieter, might have more dry grip
Tc con: shit puncture protection, short life
2.0 pro: puncture protection, rain grip, tread life
2.0 con: heavy, slower
Corsa speed 2.0 is probably a better comparison to tc.

The GP5k still looks like a better do it all option IMO. More tread and less tubeless hassle for minimal weight and W differences..

However fast they are, I wouldn't consider Corsa Speeds for regular racing.
For TT, as per Aerocoach testing, GP5K is on par with GP TT. If the G2.0 Speed improves some watts and doesn't lose on aero, is easier to mount than G1.0 (hopefully...), and maintains at least some durability, compared to G1.0, I'm on them.
Minimum bike categories required in the stable:
Aero bike | GC bike | GC rim bike | Climbing bike | Climbing rim bike | Classics bike | Gravel bike | TT bike | Indoors bike
