The big 4 (Mossberg 500, Rem 870, Win1200/1300, and Ithaca 37) are all pretty interchangeable and are mostly a matter of personal choice. I find the Charles Daly line pretty nice as well, and the Benelli nova is great as well. In the end, it mostly boils down to what feels best for you.
EDIT: WOW, I did pretty good for not seeing the poll.
