It really is the personality that counts, not the breed. I would make my decision based on that more than anything else. 
The only thing I would keep in mind is that those breeds can be a little more prone to health problems. Lops tend to get ear infections easier, and dwarf breeds tend to have more teeth problems because of the shape of their head. Not saying that they for sure will have problems and other breeds won't, but it's just a little more common for those guys.
