Evanix Rex-P .357 Best Ammo?

So I have pulled the trigger on a .357 and was curious if anyone could point me towards the better ammo to start testing with. I have heard the Nosslers are a NO-NO and that's about all I have heard. I'm not sure what the better fitting ammo is going to be yet either. .356 , .357 or .358.. My guess is one of the lower diameters.

Thanks for any input from the Rex owners out there.
