Comparing the 3, the TA is the clear winner making more power through out the range. The Thumper and Isky are similar from 4000-up, but the Thumper produces more low-end.
Gotta say these sims aren't likely to be extremely accurate since they only use basic cam specs. It's likely Comp Cams tweaked their profiles to perform better than these sims show.
