Well, for the time being, since, like, 7 hours ago, the performance on my Lumia 735 is amazing, almost no resuming screens, apps loading super fast, battery life is a lot better, and, overall, beside the same odd bugs (some icons on the "All Apps" list not showing, the background picture on the Start Menu not coloring black/White on the "All Apps" list when closing an app, Rich Capture not working at all, just showing me the message that is turned on, but it does actually nothing but take really bad pictures), I can say it's pretty much a 100% go, still need to see if in the course of the day tomorrow I didn't face some random reboots, but so far so good.
