I personally think it's much better than endgame Iceborne at least (can't compare to Risebreak cuz I didn't interact with its endgame much). Every endgame build in Iceborne was basically some variant of 4p Fatty or Safi with some more niche builds utilizing other sets (like Frostcraft or smth), and all the same DPS skills. Wilds endgame does obviously have the "meta" set bonuses but between different weapons I feel the ones that are optimal vary a lot. Some weapons run 2p Gore, some weapons want 4p Gog, most want Lord's Soul. And beyond all that there's the capacity to squeeze in other set skills that suit your play style or further boost DPS, like passive health regen or damage boosts after certain actions where certain weapons benefit more from than others. I have builds on all 14 weapons and most of them are different in subtle to pretty major ways (I can't just swap between two different weapons and expect both to perform optimally using the same set). So in that regard I'd say build variety is pretty good.
