I ran 3e with deliberate 1e feel. But I would never want to go back and run straight up 1e AD&D. And while I understand the people who are running cleaned up and modernized versions of AD&D and BECMI, I'd never switch to that either. As hard of work as it was to get 3e to run like I wanted 1e to run, it would be even more work to get 1e to run the way I'd want 1e to run.
Every single edition of the game has had problems because there is no such thing as a perfect ruleset. There are only tradeoffs. And on top of the tradeoffs, no rule set is ever perfect either. Every edition needs cleanup and extension because every designer had a deadline to meet and made mistakes. Every edition of the game did something well and something badly. You can talk about the tradeoffs, but ain't no sense in fighting over which is best.
