Seeing the videos, it's pretty much a bug-free, polished and finished version of 0.9. They introduced all the already planned features (e.g. special shot/pass button), individual tactics etc.
The base game? Pretty much the same basic non-sophisticated game, but more responsive, which is actually a big deal.
Ball physics are still dreadful and worlds, decades behind the nuanced ball physics of PES. I don't like how the only way to get a decent shot is pressing the 'stunning shot' button, & not relying on real-life ball physics to use a rebounding ball's stored energy. If the game had realistic ball physics, you can get a decent shot by shooting against the direction of the incoming ball, or timing your shot correctly. The stunning shot button makes sense only for when you're on the ball, but it shouldn't be the only way to get a powerful shot.
I haven't played of course, but judging by the way the ball defects, how it bounces and its trajectory on crossing, the ball's spin has no affect on how it bounces or behaves, unlike in PES:
Yes, the tactics are an upgrade over 0.9, but it's nothing they didn't announce before, and still way behind PES. Again, I'll have to play and see how decent the off ball player movement is, but I'll be surprised if it's anywhere as sophisticated as PES.
Overall, this isn't an overhauled or massively fixed version of 0.9, this is the finished version that was planned all along, with some 'fine tuning' to satisfy some complaints (e.g. pass speed and responsiveness).
I liked the dribbling in 0.9 tbh, and other than the exaggerated player momentum, it was ok. I'll look forward to giving 1.0 its fair day in court.
