I chose Devilgotchi!
I just bought mine on eBay, and I think they are great. I would like an Angelgotchi too, but they are a little to girly. (I am a girl, but I tend to avoid girl things) Plus, the devils are super cute and cool. It's unfair to say that they aren't good tamas because they are too "evil." It's not real evil, it's a cute and fun evil. More mischevious than actually evil. Both are quite cute, but in my opinion the Devilgotchi has a bit more character and that makes it more fun. The only bad part is the soft-screws and the price.
