I'm not terribly fond of turkey overall; the white meat is generally dry and flavorless, while the dark tends to taste too gamy. The single exception to this is properly-smoked turkey, which is excellent and will get me going back for seconds and thirds.

Chicken, now... I'll eat either white or dark meat, but tend to prefer dark for everything except making jambalaya or chicken salad, which require chicken breast. We have a friend who greatly prefers white meat, and sometimes we'll go in together on a whole roasted chicken and split it that way.
