I will add weight factor also!
For race i will go 4S and play with gearing because handling is more important.
I say that on 4S lightweight draw less avarage when on heavy 5S.
For bashing and day fun and some race 5S OK, for race 5S power usless on heavy model. If 4S and 5S weight similar and ESC handle 5S go for it
Now I personally working on my truggy to make it light as possible and one thing shave some weight on battery.
