if you re happy w 170mm, best value in 24mm is probably Riro / Racework. If you want 165mm or less, in 24mm, it gets expensive and complicated.
as long as you buy something that fits your need (length, spindle, chainring interface, Q factor, then i would treat them all interchangeably.
I ve installed 5 pairs of racework carbon cranks years ago, they re still running. i did break one NDS crank ark, but they changed the design since.
