I love the Bellas; even though I am short and the legs are a bit long on me. But the material is smooth and holds you in and the pad is much better than the T shorts. I wore T shorts for 4 years and the difference is amazing. It is worth the price difference.
I have one pair of Shebeest Triple S. The chamois is "lumpier" and i had some chafing roblems with them at first. But now the are fine. I wear them on longer rides when it's really hot.
