I'm a big fan of the spokeshave, planes etc. I use the spokeshave for the buttplate inlet (part against the shoulder) with big success too, but it really has to be sharp to but end grain nicely. I'd use a drawknife more if I had a shaving horse.
I don't have much trouble being efficient in shaping a stock. Maybe it's bowmaking that has given me skill and confidence in roughing things out quickly. The "workmanlike manner" areas for improvement for me are inletting parts (I take at least 4 hours to inlet a lock on a good day), shaping moldings around the lock and fore-end, making and installing nosecaps, carving and engraving. That's a lot of room for improvement.
