Knights
The nightrider is amazing.
the 64 squares
I would say knights, because they're tricky pieces and very flexible.
Amazon is coolest ,( is combination of queen and knight)
pawns , often first to the front line , never retreat , under rated but all pieces but the bravest or most foolhardy run when pawns advanced on them ,
Bishops , because both of them used together are very powerful in open positions
