I started with regular D&D (red box basic), then moved to AD&D 1e for the increased options, and for the seperation of race & class.
When 2e came out, I saw it as a big improvement and embraced it - I liked the increased options of specialty priests and specialist wizards and the like. I liked the class books at first but felt that they quickly went down the tubes.
I bought the Player's Options books and liked a lot of the ideas but never had a chance to use them so I can't say how well they would've worked in play (except for a few elements of the combat system that made it into a campaign that I briefly joined as a player).
Around this time, I started to become a little more aware of other games out there on the market, and fell in love with Alternity.
When 3e came out, I was excited about some of the changes but felt that not enough had been done. Consequently, instead of jumping into it, I decided to make my own rules set combining the best elements of all 3 editions and Alternity.
After wasting over a year postponing the campaign because the rules weren't ready, I decided to scrap the project and just use 3e, as the conversion work was too much of a hassle.
Since then, 3e had been working great for me & my group.
So to sumarize, I guess I fit more into the group that favors the current edition over the one I grew up with, although the reasons have less to do with me thinking it's a better system, and more to do with wanting to use the system that's compatible with the adventures and other materials now being released.
