Question on who to b6 nel or aizen

As of now my main team consist of b6 gin b2 tosen and b1 kisuke. Nel just recently came out with reruns and ofc im wondering if I should b6 nel or gin I was all in for nel cause she looks cool and seems to do a decent amount of damage...but I feel like I've already invested enough into thrust and tosens Battlefield skill works well enough... my question is should I b6 aizen to focus more on a spirit team (obv I'd pull for toshiro to) or just fkin send it on nel
