The crews are quite different and so are their gameplays.
If you like Sue, you can buy Parker starter. He's an overall good master, mostly scheme-oriented, but the Crew can also be quite deadly and hardy in combat.
If you like Viks, you can still buy M2E models, while they are available. They are a more specialized close-combat Crew and need some practice and support models. Taelor is a very useful model even out of the keyword.
You probably have some Freikorps models, so you can try Schill. He's quite interesting now. Not sure what his new starter will look like, but he has all the same models as in M2E. With equipment upgrades you can customise the crew midgame to meet any challenges.
