I have one of both
Rupert my Syrian is actually very shy and doesn't like to be handled much and he's quite cautious of everything and anything! But he's super adorable, loves anything with food involved and is a real sweetie.
Joey the Robo is like a little lightning bullet, he shoots around his tank and is such a busy little character, he's great fun to watch and loves toys and tunnels. He isn't at all shy but is too quick to handle.
I'm not much help! I think they're too different to compare really.
