They are pretty different, the one thing they have in common is top tier combat.
PGR has arena combat, is faster paced and flashier animations, has more of a focus on memorable boss fights than wuwa, but the mobs are worse, storywise it takes a bit to get going but has some absolute kino chapters, uses VN storytelling and some chapters are really long.
Wuwa is newer, so the gameplay feels more polished, the game is open world and the game has incredible visuals, so higher pc requirements, combat is a bit slower than PGR, has a slow start like PGR but gets good faster, writing is not as good as PGR yet but has better presentation with a lot of amazing cutscenes.
Also some differences in MC, PGR's mc has a established backstory and starts as a normal human and gets stronger over time until he becomes Vergil, only becomes playable way later in the story. Wuwa's mc starts as a god with amnesia, so discovering the mc's past is one of the appeals of the story, very strong in gameplay too and unlocks new elements as the story goes.
There are theories that the verses might be the same but nothing that confirms it yet.
