When assembling a face frame, which is likely to produce a better fitting,
plumb/flush face frame? The Kreg Jig or a dowel jig? I don't have access
to a planer or a wide body sander, so I won't be able to (easily) fix any
misalignments. BTW, I haven't used either one jig before so the learning
curve should be even.

What say you?
