If you really want to see the PS4 shine, try the exclusives, especially Infamous:SS and Killzone:SF, I liked Tomb-Raider:DE, however I don't get why some people prefer it over Uncharted...
I am no fan of the UbiSoft games (except Far Cry 3) so I don't know about watch dogs, but I am sure even comparing it to the previous gen effort is fuitless... but hey, it's your eyes, you decide how you can appreciate it, personally after a few months of PS4 I sold the PS3 because I could just not go back and I hope they port my favourite PS3 games to the new console, with better frame rate + resolution (These have always been major complaints of mine with most of the PS3 and 360 games, since 2005).
Among the smaller titles, I liked Strider (July PSN+ game, this alone makes your subscription worth it for 4 months), Resogun, Pixel Junk Shooter, Trine 2... Not so Outlast or don't starve.
I have been personally pleased with the PS4 so far, but maybe you are looking for something "different", in this case, the only different console is the Wii U, the xb1 has mainly the same games at lower resolutions and a couple of exclusives they try to pass as the next big thing, but they're nothing special, neither visually nor in therms of pure gaming goodness.
