I don't have the TL version, just the standard clincher & thus far I'd describe them as amazing. I also run Conti Supersonics to preserve as much sidewall suppleness as I can manage & (GASP!) Mr. Tuffy Ultralights for piece of mind.
They definitely feel faster than my previous tires [censored--for relevance] & the grip is nothing short of inspiring. I'd say at least equal to better than Vittoria Open Corsa III and much more longer wear life at least as long lasting as Vittoria Pro-Slick's.
How much "better" depends on where you are starting from. If you are on the fence, they are worth it. At $50 a piece, I wouldn't hesitate to buy another set.
When I bought mine Amazon had 2-packs for $100 v/s $80 each at the LBS.
