Gotta agree with the others. Having played and run the last few iterations of D&D and its derivatives (e.g., OSR games like DCC RPG and Adventurer, Conqueror, King System, and 3.5-alikes like Pathfinder/Starfinder), I really dig the cleanness and focus of 5E. While I actually really loved 4E compared to a lot of folks, running and playing it can become a real chore unless you’re just SUPER hype for engaging, complex tactical combat.
5E makes good incremental evolutions on the core d20 system, brings back some nice parts of prior editions, and mostly just feels familiar and warm and what your sort of platonic ideal of TTRPGs probably is.
I’ll agree with others that there are probably “better” games for any particular kind of play or story (I’ve run way more Fate Core, Mutants & Masterminds, Exalted, and various Powered-by-the-Apocalypse titles, and played way more of the above + Mouse Guard, The One Ring, Chronicles of Darkness, DCC, and myriad storygames like Icarus and Ribbon Drive, than 5E in the last 5 years), but. . .
. . . for a lot of people, settling down to do a TTRPG can be a bit of a mental lift to begin with. D&D is universal, familiar, and, like above, sort of the “default.” People see it portrayed in Stranger Things and Community and Critical Role and sort of view it as what RPGs are/should be. Countless videogames have robbed its terminology and systems ruthlessly over the decades, creating familiarity. It’s got the cultural cache and the automatic buy-in.
AKA, for someone new to RPGs, your task of getting them into things with D&D is probably gonna be easier than whipping out the latest indie press critical darling. It’s hard to go wrong with the king, tbh.
