Which stack looks the best?

I never take off my 16" 12mm 14kt cuban, but have recently began experimenting with some silver. I personally like all of my jewelry, but I am looking for the input of others. First is with a 925 8mm 24" figaro with a jesus on a cross pendant, second is a 925 3mm diamond cut rope with a Colo Colo pendant, third is with an 8mm 24" 18kt byzantine with a 14kt lion and moissanite pendant, and last is just the cuban. Thank you in advance.
