This was largely the biggest source of discontent with 4e, yeah, was that it was described by many as "Just WoW but in dnd". It ultimately didn't feel like D&D to me, even though mechanically I'd agree with many that 4e was pretty easily the single most "mechanically functional" version of D&D, but it was also the "least D&D" version of D&D. Which is a problem when you're here to play D&D. I think it's an issue not with either play style or mechanics though, rather I think it's an issue with "the game being played" at it's core. 4e was not D&D, it felt more like Warhammer, which are two very distinctly different games. Even comparing different war games like, say, X-Wing and Warhammer 40,000, you end up with vastly different games.It is a forum expression that D&D is "everyone's second choice." IMO, this was never meant to be taken seriously and is certainly not something WotC (or anyone else) would design around. It's a farcical statement. D&D is pretty obviously the first and often only choice for the vast majority of TTRPGers, given its absolutely gigantic market dominance.
The extent to which mechanics determine play style is never going to be cut and dry in a TTRPG, simply because the medium is built around the core notion that each group has final say over their interpretation of the rules and how they will be expressed in play. Even a game as simple as Dread can vary greatly from table to table. In general, the more codified the rules system, the more play style can be controlled, but if a TTRPG is over-codified, it stops being an RPG and becomes a complex boardgame (e.g. Gloomhaven).
4e is probably the farthest D&D has gone in terms of trying to mechanically codify the play experience, and this received significant backlash. 5e went in the other direction, leaving significant space open to player and DM interpretation. I prefer the latter.
If I go somewhere bringing my necron army intending to play 40k, it means I'm going to play 40k. I'll not be happy if I get there and everyone who advertised 40k is then playing x-wing, in that situation I'd just leave and go find MY game that I came to play. That was 4e's issue imo, they advertised the game as D&D that was distinctly a different game. It was not a TTRPG, it was more of a hero based war game with a handful of RPG elements.
Otherwise, I dunno maybe genre or campaign preference is being conflated with playstyle. I've played Dark Sun, D&D 2e (Planescape) 3.5 (primarily Greyhawk), and 5e (GH and FR and once Ebberon). I also recently played a mech style game, I can't remember what it was called, for several of my friends, and I have one friend that always wants to play Weird West or Starfinder. I have unfortunately just no interest in these games, the SciFi setting does nothing for me. I like fantasy and my favorite settings are planescape and greyhawk. It's a preference for setting and genre, but I don't think it should be mistaken for a play style or mechanics issue.
