Yes, obviously, a GP 5000 clincher vs a GP 5000 TR (tubeless ready). It wouldn't be very useful to compare a tubeless tire to itself with a tube in it, now would it? People who have bought into the tubeless trend aren't going to be inclined to put an icky old tube in there.

My assertion stands: a clincher tire with a latex tube can be as efficient, or more efficient, as a similar tubeless version of that tire.
