Your two choices are certainly very nice frames and they fit the bill of being both lugged steel and capable of commuting. I personally have no experience with either of those two frames, but I do have a fair amount of experience with older lugged frames that have proved quite suitable for commuting. I would personally suggest checking out the used options in your area, a great many deals are to be had out there on used road bikes of the lesser known or smaller makes that are nonetheless top-notch bikes when built up properly. My suggestion of seeking used bikes comes from my having been raised thrifty, my current status as a student, and my love for pre-owned things that have already developed a "personality" of their own. However, if you prefer more modern options I can offer little beyond Soma's and Rivendell's options. You may also consider looking into Velo Orange Rando frame which is also lugged steel and suitable for you needs. Good luck!
