Yeah, this is it. Regardless of which edition we started on, it was our first, and we all have nostalgia about it. I started in 1981 myself (so missed OD&D), but it was still a magical experience for me and I still love that edition because of that. I've heard folks who started with OD&D claim it's the best because it was the first to capture an RPG. And others I've heard say 1e is the best because of the era it was in (I've made claims like that myself). But you know what (general you, not you specifically)? I went back years ago to play the edition I missed, OD&D, and did not have fun. Trying to parse the rules was too much work. It was completely disorganized and there were a ton of gaps. I didn't start with an experienced OD&D group to teach me or run me through the game as my first experience like most OD&D fans did. The same applies to people who might have started with 3e and picked up a 1e book. The complexity and unrefinement of 1e could make it hard for that player to learn the game and/or enjoy it despite the fact that I love it and didn't have those issues (because I had an experienced 1e player to learn from when I first picked it up and the game was new to me and thus exciting discovery).Honestly, having played since basic and through each of the succeeding editions, it wasn't any more magical than any other era in which a player first encounters the game, becomes enthusiastic about it, and has more time to devote to playing and thinking about it. No edition was more real than any other, though some obviously worked better for individual players and groups than others... and will continue to do so. And some inspired styles of play better than others... and will continue to do so. And some blended various good aspects of different editions better than others.
Someone starting with 5e will most likely have the same feelings and experience that I had with B/X in 1981, and they'll look fondly upon 5e as the edition continue to evolve. One day, they will become grognards as well

TL,DR: Whatever edition someone starts with is going to be the nostalgic edition because it's the edition that unlocked the magic. And going back to a previous edition won't necessarily be any more magical because it wasn't your first. So don't sweat about missing out on learning in the 70s, or 80s, or whatever. Because you did experience the same magic. Just at a different time.
