I marked Other. I've never hated 3x. In fact, the big role out of 3rd edition got me back into gaming after an almost decade long hiatus, and I had skipped 2e altogether. It was pretty cool to see how far gaming had come, what with message boards, personal website, PDFs, etc.
It wasn't until after I had played 3x for a few years (and the great 3.5 money grab) that I started disliking 3x, eventually moving away to other games (Savage Worlds and now Castles & Crusades as well). I despise the intense rules bloat and design philosophy ("a rule for everything, and for everything a rule"), but it sure sells books to those who like that philosophy (and more power to you).
I don't have high hopes for 4e. I'll get the PHB and maybe a DMG to see what kind of neat things I can steal for my other games, but I seriously doubt I'll play it. I certainly won't run it, unless it blows my socks off, and given what I've read, smart money bets the socks staying firmly put.
