I'd personally go with a Mac mini unless I needed the extra graphics power. I've had two iMacs die within one year of purchase, and one of them died again five years after the original purchase date. It wouldn't be so bad, but an iMac has a value of $0 to Apple's recycling partners if it won't even boot. Unless you really adore the aesthetic of an AIO, I don't think it's worth the risk of losing a perfectly good monitor if/when your iMac dies out-of-warranty.
