Viper v3 vs v2 from FK1?

Looking to buy either the Viper V3 or the Viper v2, coming from the FK1. I know shape-wise the v2 is an fk1 clone while the v3 is a different shape, but i've heard some bad things about the scroll wheel of the v2 and i'm looking for something that'll last me awhile :/

v3 is 160€ v2 is 120€ (per maxgaming) also looked at the Waizowl Cloud but i think i'd rather stick to a manufacturer i know since I dont want to deal with RMAing again.
