First cleanup crew for 120

[trilinearmipmap]

What are the best choices for a cleanup crew for a new 120?

I don't have any significant algae problem as there is no bioload now.

I was thinking of ordering a few different kinds of snails and see what does well.

I have heard to stay away from margarita snails because they die quickly.

Not quite sure how to choose between astrea, cerith, or other types of snails. Also with the different types of hermit crab, should I steer away from all of them or are any types recommended?
