A lot of terrible takes I won't even engage as there is no real point. But D&D 5e is by far the best tabletop RPG...it strikes a near perfect balance and level of complexity. I will leave it at that.
Unless you want to do anything non combat related, have deadly combat, "combat as war", make noncombat characters, play other adventures besides combat centric ones,...
You get the idea. It does a tiny subfraction of RPGs reasonable well (although I would hardly call it best), but even there falls flat with unclear rules (which they then gaslight as being unclear on purpose to allow DMs to have control...) and things like the D20 making character attributes and skill just a secondary factor in success chances. But for anything else, including more modern combat scenarios, D&D is very bad.
The only thing D&D is really the best in is that thanks to its age and marketing its easy to find groups to play with.
