Fueling & Injection - which to choose

Im in the process of piecing together my fuel system and Im going to run 2 in tank pumps. I either want to use 2 walbro 255's or two aeromotive 340's and i cant decide which to use. Iv heard good things from both. I would like to know which y'all would use

walbro is easier on wallet

Walbro have proven most reliable.

Thats what iv heard. Since the aeromotive pumps haven't been out to long is that the reason most haven't used them cause they don't know?
