I've found that Syrians often tend to be a lot more sociable, and enjoy human contact. I've always had lovely cuddly Syrians who loved coming out for hugs. One of my old boys Toby used to perch on my shoulder as I walked around the house, or sleep in my pocket.
As already said, they are often quite easier to tame. They also love food (all of mine have been proper greedy guts!) which makes them so fun to spoil.
Whereas a dwarf might like to dig around and forage, and do his own thing, you might find that a Syrain will be swinging off the bars waiting for you to let them out for their cuddle!
