I like both! It really depends on the breed and gender tho... I find male "teddy bear" syrians and male RWW (Russian Winter White) Dwarves to be the calmest tho. Roborsky (spell?) dwarfs are very tiny and cute, but are funner to watch than hold. 
I have a female RWW. (If that means russian winter whte.) She is just the cutest. but she bites. any advise on how to stop her from biting?RWWs: because of their social habits. My 2 males are just a delightful pair.
My male hammie is quite calm.He is calm,if he is not running in his wheel or ball.He is really friendly as well.My sister also has a male hammie and he has a very similar personality to my J.J.thank you for the advise petluvr01.
And i always thought that female hamsters were calmer. (I was told by a friend...)
she was 8 weeks on the 29th. I got her from a petshop in Beeston. (you wouldnt know because you probably dont live in Nottingham, England...) But its a very good petshop. ive had her since she was 6 weeks.Well, Idk. I have had one female and two males (currently have a male) and they are about the same. It just depends on the kritter. My little boy that I have now is very independent and doesn't care about getting out much, where my other two (female and male) always wanted to get out. How old is your female? And where did you get her from-petstore?
