You can argue the Upper Deck boxes contain other "hits", but only top autos pull the same as a sketch. Holos and plates generally don't make back the box price.
Actually there is a HUGE difference that you didn't mention.
Rittenhouse had a controlled release date, with loyal major dealers who release thousands of sketches all on the same day.
Upper Deck, not so much.
