i don't think it is as simple as get bigger is better always or get smaller is better always. the fact you are in between sizes suggests you have unusual proportions. so depending on how you are unusual you might be better going bigger or smaller.
i am odd in that i have proportionately longer torso to legs so i will be better off going with bigger and lowering the seat.
