The RP/h *SHOULD* be about the same if you DON'T use any kind of planes in GRB and always finish your battles in ground vehicles.
In GAB you spawn planes as a killstreak and the RP you gain in those during the game gets put into the tank you are actually using.
Also in GAB a full lineup is just 3 vehicles, that also matters because the gap between you and a paypig is theoretically smaller.
This said, i also say this because of extensive personal testing:
with the 9.3 Chinkazoid premium lineup (Type 69 IIG, WMA301, Type62n545):
>GAB: Comfy 80.000RP/h
>GRB (Only these 3 tanks, no planes): Sweaty 55kRP\h
Obviously personal preference and attitude matter, i'm an extremly good GAB player.
Talking about CrewRP, GAB is way better and honestly i don't know why.
