I've been playing D&D since 1981 and I love 5E.
I played BEC and 1E extensively and loved those too, played 2E quite a bit and thought it was ok, not as good as 1E but still great. Played 3E some, it was ok but a definite downgrade. We tried 4E for one adventure and absolutely hated it and 4E drove us back to 1E swearing off any newer versions. We kept on playing 1E in our group and by 2016 had lots of turnover new players joining, old ones leaving and had some younger players not even born when 1E was published. We saw no point in ever moving to another version and if you asked me in 2015 what I would be playing in 2025 I would have told you 1E AD&D.
We did not participate in the original 5E playtest and we kept playing 1E until around 2016 when some of the younger players suggested trying 5E (they were playing 1E at the time and enjoying it). At their urging, I reluctantly went out and purchased the Phandelver starter set and gave it a try. We loved it, switched immediately to 5E, bought some new books and never looked back.
Additionally, I personally liked 5E so much I actively started looking for additional gaming groups and looking for groups online.
I played every version of D&D since 1981 and played 1E extensively right up until we switched and I think 5E is substantially better than all those other iterations, much better than some of them. I am well versed enough that I could DM a Basic, Expert, 1E or 2E game immediately, right now, with no brush up at all and I have the books to do it. I think I could manage a 3E game with a little study. I would not waste my time with 4E. I "barely pay attention to those old games" because 5E is just a better game in my opinion, both as a player and as a DM. Its just like I barely play Checkers, War or Gin any more, but I play Chess, Hearts and Pinochle quite a bit ... those games are just better and more fun for me, so why play the others?
