I've played in a steady Sunday night game for a a couple of years or more. It's been pretty amazing. I managed to get my Warlock up to 16th level, the highest I've ever managed in 35 years of D&D. The system has adapted well to our dirty tricks under one of the best DMs I've played with. I've played a total of three characters in the campaign, but my Warlock is definitely my favourite. Had I know it would last so long, I might have chosen my class more carefully, but I have no regrets.
I ran 5e D&D campaigns for a couple of new groups of players. Both groups wanted me to specifically run "the new D&D" for them. Mostly because they had bought the books but didn't really understand how to use them. Partially because they wanted to play the new shiny D&D.
The latest D&D is a pretty good game. I like the addition of backgrounds. The different types of each class that are chosen between 2nd and 3rd level remind me of the kits from 2nd edition. The feats are no longer overwhelming and merely add some colour to a character. There are enough player facing choices that t's easy for two characters of the same class to be completely different in play. All in all, it's pretty good.
I do find it fiddly at times. I don't like how much I need to consult the books during play, but it's not too bad. It's far more streamlined than the 3rd and 3.X editions. Left to my own devices I would play something more old school, but the best edition of D&D is the edition someone else is willing to run for you.
