For me personally, a 3-season TQ is overkill for summer hiking when I would want to use a TQ as a blanket. Using the 3-season TQ in the fall through mid spring time, this TQ is ideal. Not sure where you plan to use it, what the night time temps would be, but if the temps will be below 60*, I'd go with the sewn footbox. Less chance of the footbox coming undone or other "mechanical" failures occurring. If you are going to be doing your hiking where the night time temps are hovering around the 70* mark, maybe consider a summer weight TQ with snaps.
I like the idea of combining a summer weight TQ (w/ snaps) with a 3-season TQ (sewn footbox) to provide winter warmth. Best of all seasons !
