Neera vs Dynaheir

I currently have a party of

me (Mage)
Minsc
Imoen
Dynaheir
Rassad
Neera

Im toying with getting Branwen for the healer part, plus i heard she is a good NPC
Would you pick neera over Dynaheir? is Dynaheir a good NPC with minsc? or maybe drop Rassad for Branwen?

This is my first time playing BG1, finished BG2 a few times but I only started this one and stopped some time in the past
