Which is the best pet?

I had a male holland lop bunny but sadly he had a issue and i was unable to afford to get him fixed so i gave to a family that could. I was thinking of getting a FEMALE bunny or a syrian hamster. Then i came upon a guinea pig or leopard gecko!!! I cant decide i know the care for all of them and i have enought money also. So just tell me what you prefere and your experiances thanks!!! Are sugar gliders good pets? Haha i no too many options!
