I played 1st edition. But we very quickly moved to 2nd edition when it came out. It fixed some things and a lot of the supplemental material you'd want to make up your "core" game, came out for 2nd, not 1st. I think I get your point but I can't imagine many people who wanted to play 1st not agreeing that 2nd would be an improvement again.
I don't think there's really any 1st vs. 2nd, tbh. There is (1st & 2nd) vs. 3rd. And there's (1st & 2nd) vs. 3rd. vs 4th. 5th was largely a group of 3rd ed. grognards dancing on the corpse of 4e when Catalyst Game Labs screwed over the developers of 4e and turned to the Hate Brigade to produce a new edition so 5th is in many ways an attempt to get back to 3rd (but constrained by resource and ability to do so). So I think the break downs tend to be:
With 3rd vs. 5th having some preference divisions, but 1st vs. 2nd not so much.
Admittedly, it's been some years so I could be off-base. I wont touch Catalyst Game Lab products to this day. And nobody in their right mind wants to play 6th.
EDIT: Uh, no offence
