Let's face it: Lara got a limited exclusivity deal which set off a lot of the vocal majority, Sony fans. I still remember all the embarrassing threads and posts around that situation.
Add to that that uncharted is an exclusive and given that fact, there is a certain additional hype around that. Remember the desperate attempts to generate hype for the Order and how the situation was close before launch when it was clear how bad that game was? I remember several bans on this site alone.
Nobody would've given a flying fuck if the game would've been a third party game.
And add to that that uncharted is more or less the “chosen one“, the mascot Sony never had, set to outdo its biggest competitor, halo, and it seems they managed to achieve that.
And what of people who like Tomb Raider 2013? I mean, I loved that game so much, it made me but a PS4 the day it released. Maybe people just like what they like or prefer what they prefer and (hopefully) any console war bs is just relegated to a minority of people.
Btw, The Order isn't even really bad in my opinion. It just had a lot of high expectations, being on of the most anticipated "real" 8th gen games.
