On a relatively recent (at the time) processor and ideally more than 1GB of RAM and it was absolutely fine.
It's reputation for instability was heavily due to early NVIDIA WDDM drivers being utterly crashtastic - this is something that did eventually get resolved. At the time I had an ATI card and it was perfectly stable.
Source: Over the years, an app I had my hand in was on one of the rotations.
I think 11 is more about changing hardware requirements, requiring a TPM. The UI garbage seems more like an opportunity to try new things, they'll figure out that people don't like these new things.
I personally don't like the lack of old things. Namely being able to drag to the taskbar. That's baked into a lot of my workflows, and I can't believe they removed such a useful feature.
8 and 8.1 were the last death throes of decent design, and then they started making a mess of everything in Windows 10. Not only didn't they reverse it with Windows 11, they doubled down on it when they had a perfect chance to rebrand with a "back to the classics" comeback to Windows 7-like UI without backlash.
Their trajectory is locked in. Barring a miracle and re-prioritising on their users, "good" Windows releases are dead forever. Looking forward to the LGR Retrospective on "Windows 7, the last good version of Windows" in about 10 years time.
IIRC Win7 was the one that started installing most drivers without any user effort, which was really nice. It also bloated minimum disk size to many times that of XP (or a very full-fat Linux install, so the drivers can't be the reason, since that also includes tons of drivers) but if you had the space, it was worth the trade-off.
Talk about timing...
