I can't say I hate any of them, but when I'm fishing at the local pond I hate always catching bluegills and sunnys when there are bigger and better things I could be catching...and as far as my tanks go, I wouldn't get parrots or discuss because parrots are nasty little bastards that no matter what I have tried putting them with they still pick on everything...and discus I think despite their nice colors I think they are ugly and people are being ripped off on their prices when they are a dime a dozen, just my opinion I know they are very popular and my grandfather breeds them, I could get them for free but I just don't like them.
