Functionality vs appearance? I don't think it's fair to boil it down to such primitive comparisons, but in the end, I know which is more important to me on a day-to-day basis. (I say this as an extremely heavy user of both Eclipse (java, antlr, etc) and (G)Vim (python, scripts, go, etc). I can't believe this is a controversial or downvotable post, especially given the context of this article. The feel of tabs is relevant given the dozens of other niceties that Eclipse provides over TextMate? Really? Again, if you're seeking the features provided by an Eclipse/equivalent?
