I would love (sort of) being El-Aurian. Long-lived, technologically advanced. Most people already say I'm a good listener . Got spanked by the Borg but I, at least, would shut up about it once in a while.
I would hate to be Yridian. Looks like a hairless skunk (specifically reminds me of an old D&D creature called a Witherstench) and is distrusted by pretty much everybody. It's like someone said, "Ya know, I like the Ferengi. Do you have anything uglier and more untrustworthy?"
