I'd go with Uncharted just because the userbase is nearly double on the ps4 and the game is sure to be heavily bundled, especially if Sony remain light on any other first party offerings coming towards the end of the year.
Still though, it isn't exactly a bargain in comparison to MCC nor does it have multiplayer or is it completely updated like H2A in MCC. Plus all the games were released last gen and will still be fresh in the memory for a lot people who maybe are not too bothered to pick them up again and even uncharted fans may have trouble finding a reason to buy it apart from the beta if they have already played through the campaigns a lot.
