Mandos or Rebels?

Hello there everyone! This may be a dumb question but I’m torn between two ideas. I have been dying for a Mandalorian faction to come to Legion but I have to say I’m slightly disappointed that in the box it seems to be the same three or so sculpts with slight variation. After seeing that the Mandalorian Warrior units would be useable by the Rebels I think I might actually enjoy getting the Rebel Starter Set and a box of Mandalorian Warriors to add to that army. Would that be a smart choice or would that unit not meld as well with Rebels?

I’ll also add that, although I’m going to try and get some friends into Legion, I think I will actually end up using these more to paint/use as minis in our tabletop Star Wars RPG games.
