I didn't say Tree Style tabs were better, only more usable (for me). I can have 30 tabs open and see a pretty wide portion of the page title. I sacrifice horizontal real estate (which is often wasted) for vertical real estate. I can understand not liking tree style tabs for various reasons, but saying that their improved usability is subjective is a bit of a stretch.

If someone only ever has 3 tabs open then tree-style is a waste of space. How is it not subjective? It depends entirely on the user's browsing habits.
