My two brothers (Orson W. and Lurker W.) live in Stuy Town/PCV. One prefers David's, one prefers Ess-A.
As I live in the hinterlands of Virginia (where we actually have some pretty good bagels, baked by ex-New Yorkers), I always request some NY bagels when they come visit. I generally ask for Ess-A, since I've had those more and like them a lot. But should I be asking for David's instead?
