The two are totally different games from one another and both are must play for what they get right do so well in their own right.
You essentially have possibly the best Western rpg (i preferred it to Fallout4 and Skyrim) and a collection of the best action adventure tps games.
I would say get uncharted collection, finish them, trade them in and get W3.
Uncharted collection takes about 12-15 hours per game if you play them once each. I usually play them twice. Once for the story and once again to get all the treasures and take in the scenery.
I beat Witcher 3 with most of the side quests completed by putting in about 70hrs. It is very much possible to put over 100 hours. My friend is totally hooked on Gwent.
