I wouldn't say they are overrated because I haven't seen people going nuts for them. Maybe a couple of the more popular ones are. I actually had no interest in them until Bam moved to my town. He's one of the best jock types I ever had.
Not more than wolves; I feel all the wolves get more love than the deers... Though since I'm a fan of both wolves and deers, my towns mainly consist of these xD The only deers I don't like are Erik and Fuchsia. For the wolves I'm not a fan of Lobo. The rest I love!
