Fx- 3 vs 4 Stage on 480cc

Hi everyone. I'm pretty new in the forum so i don't know if someone else ask the same question.
I'm about to own an Fx Royale with a CF bottle 480cc and i can't decide wich pump i should buy.
I know a tank is a better option (or at least easier) but is hard to transport and I'm 18 so pump shouldn't be a problem.
Wich pump would you choose? The 3-stage or the 4-stage both Fx (i know the 4-stage fx pump is 3-stage also but is more expensive too). I'm planning to fill the gun to 220-230 bar. Tanks in advantage
