In terms of quantity and variety, that's a huge list. I expect only Nintendo have more, but the Wii U is in a totally different situation to the One/PS4.
There's no shortage of games to play on the Xbox One. Personally, I'm not really swayed by exclusives though. They're an annoyance, not a boon. It's great that the industry is becoming slowly less focused on them, with the best games and the biggest releases increasingly being multiplatform. I wouldn't buy an Xbox for Halo. I wouldn't buy a PS4 for uncharted. The console I own has more to do with which one my friends have than anything else. Exclusives just define which games I'll be missing out on. Overall, thanks to the large number of great multiplatform games, both the Xbox One and the PS4 have more than enough to keep me entertained.
