I've been using Edge almost since they started testing with the Chromium engine, as part of one of the fast-ring insider builds of the OS. I'm a big fan of Edge over Chrome, especially recently with the addition of Edge support for standard Chromium browser extensions.
As for Windows 11, I've had basically no issues at all and I think I like it better than Win10. I know many are unhappy with the advertising; I've not seen any of it. I suspect it's because I've piholed basically everything in my house which does a really decent job of killing a ton of tracking and advertising on the rest of my home devices (Rokus are super chatty to the outside, so is my bigass Samsung TV.) As for my personal laptop, I run pihole as a VM under Hyper-V for bandwidth savings while on the road, and it seems to murder all the inbuilt advertising there too.
All that to say, I have nine Windows devices in the house between various desktops, laptops, tablets and one Lumia 950XL phablet running WoA, and they all run various versions of Win11 RTM or insider builds. Except for the Lumia phone which is a full-on hack job, all the rest are in-place upgrades from Win10, at least three of those are in-place upgrades from Win7 and one is an in-place upgrade from Win8.1. The only PC I've fully installed Win11 from bare metal is my new-ish gaming rig I built last year.
The only thing I'm still unhappy about is how they've buried the full image backup option. It was difficult to find in Win10, it's nearly impossible to get to in Win11. I know MS would rather I just use their file recovery and OneDrive to magic everything into recovery, but that doesn't solve for other problems I'd prefer to avoid. I'll probably end up creating my own ImageX-based backup process to replace what appears to be a function they're trying to ditch. Sad face is sad
