I've never used the latter, but they certainly look very similar! I may have to give it a shot actually.

I've been trying Sidebery since about 2 minutes after I made my last comment, and I think I like Sidebery more--and I've been using Tree Style Tab for _years_

Sidebery responds noticeably faster, and the panels are a great feature.
