I'd go with the Railman for a single reason: you could one bag it using the front pocket for your laptop if so you chose/need.

I'm not a fan of the Load Warrior and LL Bean's design that opens to the front vs to the side, as those bags tend to bulge a lot even when only slightly over packed. Nor do I like the zip away handle some Eagle Creek models, such as this, have since it takes a little longer to extend it but I love their "equipment handler" to carry a coat or helmet.
