I think
@Matt10 might be a better man to answer to that question, since I don't play with lower-league teams (I'm still a kid at heart). But, for what is worth, I feel huge difference between each player, you can feel the weight and the individuality A LOT more than on any of the later versions of FIFA. Even between top players.
I'm telling ya, 16 is the best all-around football game once you apply all the mods and stuff I mentioned earlier.
I'm using Supernova's gameplay mod (the latest version) and it's so good. I can't get past Professional difficulty because I'd get my ass handed to me.
I've been trying to think of something negative to say. Like "I just wish FIFA 16 had more...." but I honestly couldn't.
If you take away the fact that graphics-wise it's still a 2 year old game, then there's nothing else to say. And even if you were (which I know you aren't) a graphics-whore, once you get a good Reshade and a few other mods (LOD mod, turfs mod, etc) you wouldn't go back to FIFA 17 or 18 for the graphics.
Players Individuality - Got it
Faithful recreation of team styles - Got it
Variety and Randomness - Got it
Careful positioning and thinking before shooting (or else the ball will end up in Row Z) - Got it
AI making mistakes - Got it
AI being smart - Got it
Pretty good Team tactics + strategies - Got it
I don't know man...
I'm addicted to FIFA 16 now.
