3.5 minus lots of core. 3 ToB classes, the Scout, Beguiler, Warmage, (buffed) Healer, Warlock, + lots of alternative class features like PHB2 and Unearthed Arcana is pretty much perfect 3.5 to me.That's part of the difficulty of the poll. We all probably like some elements or bits and pieces from various sources, but on the whole, where do we lean? I currently play PF with all splat but I actually prefer 3.5 with all splat, especially the later stuff. If you could only run one, which would it be?
cough...cough....Divine Metamagic....cough.......- but rather opening up the splats causes the number of possible combinations to explode, and some of those are very badly broken (especially when combined with the PHB Cleric, Druid, or Wizard).
