I feel the opposite. Here are the reasons I prefer PES...
1. No goal is ever the same.
2. You can save replays on your HDD.
3. You can pass the ball how you want to (I especially love the flow of the back heel passes. In FIFA I find myself saying: "I didn't pass it to that guy." It frustrates me to no end.)
4. Scoring a goal on the harder difficulties is really a challenge.
5. UEFA Champions League / Master League / Be A Legend
*I am an old-school FIFA Fan. I had the initial release in 1994 for the Sega Genesis.
