The Filson looks more "businesslike," IMO. The Yukenten bag -- if it's the one you're talking about -- is a little more casual. That Filson is a beaut. I'd go with that. Plus, it has a lock, which you may not use regularly but is nice to have. I used to have a similarly styled bag that I got in Europe (no brand -- you used to be able to find them all over the place for about $150) and loved the dimensions. Unfortunately it was stolen out of my car.
