As some one who's played every game in the series except for lost legacy and as some one who at the same time absolutely doesn't care about the franchise, I would have to say 4 was actually my favorite with 3 in second place, again that doesn't mean much since I dont really enjoy the series much.
(unnecessary story time skip if you want) Uncharted 1 was bundled with my ps3, and I played it months later when I had nothing to play, I thought it was decent but nothing I was invested in or cared about ever playing again, so I skipped uncharted 2, than uncharted 3 came out and I was over a friends house and I played it on his 3d tv (back when sony tried making that a thing) enjoyed it way more than the first but still didn't care, than they had uncharted golden abyss for vita free on ps plus, I played it and again didn't care for it but needed something to play on my vita at the time. Than when uncharted 4 came out a friend of mine who lives and breaths uncharted begged me to play 2 before I played 4 which I wasn't planning to but he gave me 4 since he accidentally got 2 copies of the game sent to him, and I was just sick of the series so I didn't really find any enjoyment out of uncharted 2. SO than finally came the time to try out uncharted 4 since I would feel bad not playing it after he gave me a free copy, and I actually enjoyed playing that one, I thought the story was entertaining, nothing great, but it kept my interest, character wise I never cared about anyone aside from Sully but I did enjoy seeing Drake and Sam interact, the gameplay especially actually kept my attention since the other games In the series bored me with its gameplay within the early hours of the game. And lastly I actually enjoyed the slow moments. So I can say it was the only uncharted I actually enjoyed playing start to finish even though I absolutely dislike Rafe and Nadine. But still nothing I would ever want to play again.
