If I had to rank them it would go

Identity

Ultimatum

Supremacy.

I feel like the action could've been shot better in the 2nd and 3rd and it was quite repetitive e.g we've found Bourne activate the asset, oh wait he killed the asset. Do we have another one? Good activate that one. Find Bourne kill him!!!

I also feel like the endings were way too anticlimactic in the later 2 but overall I love everything else about them tbh.
