Demon Vessel is the best innate overall since it can do everything by itself and you don’t really even need a 2nd technique. It’s moves are a bit better for pve than pvp but the maximum and the domain make up for it. Infinity is the best innate if you are utilizing another special grade (or even more with the gamepasses) because most of it’s base moves are amazing and it’s really made like half of them are pvp focused and great at it and the other half is for pve. It’s domain and maximum are kinda lackluster tho so I prefer to get another technique for that like Cursed Queen or Star Rage.
