Exactly how I see things. To me it doesn't feel like PES19 is on rails, but instead feels more 'stable' (due it to its simplicity) in the way things occur on the pitch and how players are controlled. Its a hard thing to explain, but this so called stability is what in my mind helps make the players feel more solid (weighty), and the great thing about this year is that they've also introduced more realistic first touch animations (taking a millisecond of extra time to control ball, hence slowing the game down), and the better backswing animation when passing. Anyways, back on topic - I agree that Konami's PES is far more basic/simple in its gameplay (talking more about the way animations respond to commands, and how players interact with each other) and variations, compared to FIFA. But I honestly reckon this is genius from Konami's part. This "Keep it simple stupid" approach on the ball and with its gameplay, not only makes the game easier to control (this is my personal opinion - yes, I find it easier to play and control players on full manual in pes2019 compared to fifa19) but also makes the game actually look more realistic when watching. For me, when I played (as well as watching the youtube clips of gameplay) fifa19, there seems to be too much going on, including the weird running animations, weird quick panning of ball being passed around pitch, foot sliding (not saying there aint any of this in pes) - which together adds up to a big old mess.. kinda like this post

I just think less is more.. and I think both games still need to work on things like introducing more 'walking players'.. and limiting the 'everyone on the team must be running around like headless chooks' thing, which would make both games appear that much more realistic when actually watching the game on the screen.
The point about which game (pes or fifa) represents the real tv football the best is so subjective. I exclusively play PES19 atm, so naturally when I watch football from various leagues on the tv.. I actually get reminded of PES.. and I think pes19 represents the real game better than any football game to date. Im sure if I played fifa all the time id think the same about fifa. But for me, and knowing what I don't like about this year's fifa (poor animations and too much going on for my liking), fifa19 doesn't represent how I feel about tv football or the real thing at all. But again, how one views realistic looking football and how its best represented is such a subjective issue.
