Both types make excellent pets for different types of people. Syrians are good for children as they are easy to handle but they have to live alone. Dwarfs can live in groups and are lively and fun to watch but can be harder to handle as they are small and quick. Robos are lovely to watch too but can be hard to handle are are really more suitable for adults. Chinese can be lovely but again are small and speedy and some lines can be agressive. My favourites personally are syrians though I have kept dwarf in the past and will probably have some again soon
