As p1 +nin works better. +Crit might work only vs nin/crit scalling kushina, but you are very likely to lose 1v1 in that case anyway. Crit also only increases(decreases) you chance of landing(receiving) a critical attack, which, as p1, you should be doing relatively often anyway. This scalling doesnt change the ammount of damage you do with critical attack, just the chance of performing one. While this might be tempting, because vs anything other than nin/crit kushina you'll get to the point where you always crit and never receive crit, you simply wont have enough damage against meta picks like kakuzu or minato.

+nin on the other hand increases your damage progressively during fight, both on critical as non critical attacks.

+Crit is to be considered only on p2/3/4, as a defensive stat to increase bee's survivability. That is until the point, where your p2 is almost as stacked as p1, then +nin is the way to go, as you shouldnt need extra layer of defense then. But this particular scenario, given you have 110k bp, will propably never be your case.
