Love, but kinda by default.
Earlier editions have enough inherent flaws* that I don't think I could realistically play them.
Check out the 4e version of this for my 4e thoughts.
So 3e is kinda what I'm left with. While its still a beast in a LOT of areas (HL play, for example) I generally find it the best mix of classic elements (spell slots, 9 alignments, etc) and new innovation (upward AC, skill set) that it feels the best mix for me.
Pathfinder addressed many of my gripes for now, and the wealth of modules and supplements insure plenty of options for me in the future.
* By flaws, I mean things that bug me enough to not really play it further, like downward AC and some inherent class balance issues. My nostalgic itch can be scratched by a retro like Basic Fantasy.
