Are these games better than FIFA or are they both quality? (I know nothing about soccer all the way but I remember having fun on Fifa on PlayStation)
Both games are quality, but it just depends on your preferences. It's like deciding between getting a Galaxy or an iPhone. You're not really losing out with either other choice, but one probably fits your personal needs better.
If you're not big into soccer I would suggest FIFA, because it's a lot more playable for a casual fan that just wants to have fun and the learning curve isn't very steep. PES is geared toward people that are hardcore fans that want as real of a simulation as possible. Which is cool, but it probably wouldn't be very enjoyable for somebody that just wants to have fun and doesn't care about the authenticity of the game play.
