IME Crown Heights is #1 for flavor (get Whole Wheat). And probably bottom of the list for customer service.
Also freshness is meaningless, it's the packing that counts. You want your Matza packed in corrugated cardboard boxes, not in plain single layer cardboard boxes. As long as humidity is kept out, it will be nice and crisp. Also IME if you get late in the season (at least in Crown Heights) the matzos tend to be thicker (possibly workers already worn out?)
