The extremely short and biased answer you'll find from me is this:
3s and lower, XT60.
4s-6s, XT90.
6s-10s, XT150.
I can bore you to DEATH with wiring gauges, peak current draw vs voltage, wire lengths and total amperage requirements, but the above works in my real world applications and I have experience with all three types.
Your results may differ.

Yeah, from what I had read it sounds like xt60 would probably be ok but I will go ahead and spend the little bit extra time and money to use xt90s for the extra peace of mind.
Thanks Steel Rain for helping me make up my mind.
