A check on the specs indicate Bottom Brackets Drops of
Surly Cross Check 66 mm
Salsa Casserole, 76 mm
I think the Casserole with the standard Bottom Bracket Drop is the better choice for normal road riding. The Cross Check is more for cross country, and the short BB drop provides extra ground clearance, which is not needed for long distance road. Note, a Waterford Road Sport (for long distance) has a 80 mm BB drop.
