We have upgraded 4 computers to Windows 10 since Friday. We had reserved the upgrade and it just popped up Thursday on the first one and asked if I was ready to upgrade or schedule it. I chose schedule thinking I would wait a month or so, but I only had Thursday, Friday, or Saturday to choose from. I chose Saturday a 6PM so that I would have time to do a back-up and an image before I did it. It went flawlessly.
I like it. I like Edge, but have not been able to fined an Ad Blocker for it. It sure has zillions of ads, even when I opted out of most everything. So, for now, I am staying with Firefox with AdBlocker Plus for my default browser. and I can keep my favorites folders in the left sidebar. I still click on the Edge a couple of times a day just to become familiar with it.
