Denver is definitely the best job out there now. In NYC, you have to deal with the Favre circus, the most cut throat media in the world, and well, New Yorkers. In Oakland, you get...well, no need to kick a dog when he's down. Cleveland, though attractive, breeds a culture of losing in its ownership, its fan base, and its players. Plus it's ****-all cold in December and January. Detroit: see Oakland.
Denver wins by default, but really is a plum job. An owner who will make winning his first and only mission. A fan base that is unique and rabid. A city that is beautiful and an short flight from anywhere in the country. A franchise QB, WR's, and O-Line in place already. A franchise that NFL players WANT to come to. A top 15 draft spot + 8 picks. A team in a division that is ripe for the taking--9 wins may win it.
