I don't think the lines at B are all that bad most of the time. The only time I see them taking more than about 5 minutes to clear is on Monday mornings. I fly out of B at least three times a month and rarely have a problem. I still really prefer E or even C, but I don't find B to be all that bad (provided I'm not doing a B84 flight).
