First played in 1993.
D&D 1993-1994. Used the Black Box for about six months until I got the 2e PHB. No more RC at that point.
2e 1994-2000. At first it was just PHB supplemented by D&D until I picked up the other core books and then expanded my collection. Ran and played a few different campaigns until June 2000.
3e 2000-2004. Ran online games at this point. Eventually, the campaigns fell apart and IIRC, I had problems with one of the services I was using. The 3.5 switch didn't help here either, but it really wasn't much of a factor in the game falling apart if at all. There was also the pbp game I tried running here around 2010, but that fell right apart on me as I didn't have a good feel for running a pbp game.
2e 2014-2015; 2018. Ran a campaign for my sister and her kids, the RL stuff kept disrupting things. I went with 2e because I had published adventures for it and I didn't want to put a lot of work into campaign building if her kids didn't like it. Played about three sessions of 5e here because my younger niece wanted to DM but I think she got something of a rude awakening when she found out what things were like on the other side of the screen.
