They're both good franchises, but I always liked how Uncharted was about fluid movement and platforming. The multiplayer was also more fun and silly (where you can summon things to reek havoc). It also had more verticality to the maps. In other words, it's the opposite of Gears. Plus, the cast of Uncharted were cooler and more charming. The campaigns also had some cool set pieces (like the train in Uncharted 2). So that's my pick. But I am playing Gears 5 multiplayer and it's fun, just different.
