My systems of choice are (in order) AD&D1E, Moldvay D&D, Holmes D&D and BECMI. Pieces of later editions serve to clarify rules, offer new monsters or magic items, or to be mined for great ideas.
The idea that someone's commercial "system" can replace mine is laughable, in that sense. I started parting ways with the party line when Gygax was kicked out in 1985. The fact is, I make better DMing decisions when I am comfortable with the rules, milieu, characters and master framework, so my rules are always the right ones. My play is noticeably more clunky and inferior with 2E and beyond, even if I'm well-versed with the rules.
Then you add this in to the nostalgia factor - friends, music, movies, culture - of the time when you fell in love with D&D. I don't care if that's 1974, 1980, 2000 or 2009, it is an inherent and irreplacable factor in the game's atmosphere.
The best edition of D&D is the one that gave you your first "wow" moment, the one you fell in love with. I used to be mocked for that sentiment but curiously, now that the 3E and 3.5ers are feeling the pinch of 4E and the splintering of the player base, I find that players across the spectrum are more mindful and empathetic when it comes to what is important to you and why.
TLDR - D&D is the players' happiness. The players' happiness is the DM's skil in presenting the world. The DM's skill is the comfort with the rules. The comfort is the first edition you loved. This is why getting groups that are willing to share the same experience is such a crucial thing.
I agree with this with the exception of the last part. The DM's skill comes from both comfort with the rules, practice and a bit of natural flair.
Your best edition might be your first or your last.
I loved playing 1e. I loved running 2e. My system of preference is 4e.
