Most lazy people use Tris because there's a 1 M stock solution - but you can try also other buffers as long as you stay in a pH range >pH6 <pH10. Of course you still need imidazole for the elution but the buffer might bring some surprises, one of them can be a better initial purity after the first capture step, another one might stabilize your protein.
