Is the difference between a level 10 wizard with 13 feats (pathfinder alpha) and 7 (Core 3.5) is 'close enough' for you, then more power to you. It it's a pretty vast power gulf, from where I play, though. I'll likely play 3.5 still, with people who like the skill granularity, and optimization, and broad array of choices. But I won't convert old pathfinder products to 3.75, or new ones to 3.5. Especially not if 4e is as simple for a DM to worldbuild with as it seems.
