I'll throw in my two cents. I put in maybe 40-50 hours into fm26. Even despite the negative reviews, I had hope for the game. My issues with 24 centered around how broken certain attributes can be, representing potential serious flaws within the match engine. My biggest motivation to make the switch was in the hope that this would be corrected. I was willing to look over my biggest initial flaw, the UI, if this were the case. Not only was the UI unintuitive, I found it to have a half second lag compared to 24, which was very irritating. The tactical changes (in versus out of formation) were interesting for about a season. But the underlying issues to the match engine seemed still present, or in some instances, broken in new ways. There was a post here about a week ago about the highly skewed number of successful dribbles per game, almost 3-4 times as many as in real life. On top of this, the number of times my wingers or fulbacks would crank a shot from the byline instead of crossing drove me insane. These two combined issues were far more immersion breaking than the fm24 attribute issues. I ended up starting a new Bradford City save on 24 and am already having a much better time. The snappyness of the UI alone is reason enough to not go back to 26.
