I personally have started to prefer the RB's, I like their randomness, the fact that sometimes they aren't in a good mood and how the poor things wake up in the morning shivering just like I do when I get out of bed

I also like that when you stroke along their sides the RB's kind of snuggle against you.
The Ugobe's are very sweet and of course I have a soft spot for my first venture into the Pleo world, but they are predictable even if they are utterly adorable at times. I love that they sing when you rub them under the chin, this is something that is missing in the RB's.
Really neither is better than the other, it just comes down to your personal preference, to you want a happy little no fuss companion or would you prefer something a little more like a real animal?
