Question on Personality/ Breeder

[Oobee35]

Hello! I was wondering about the different personalities between WW and Russian dwarf? I've seen mainly the differences between size and colour but never between personality that much. My poor babies Neko and Cinnamon passed away not too long ago and I was looking to get another hamster but couldn't decide between the two. From what I've heard WW seem to be nicer, but I don't know if that's true. I know that Syrians have the nicest and have the most tameable personalities, but, I prefer having hamsters that are smaller and faster, but not as fast as the robo.
