I am a PC addict, with about a dozen PCs that I keep running, for various reasons. I was a Microsoft DOS fan until they introduced Windows 3.1. (I never tired Windows 3.0). It was the worst thing I’d ever seen. I was a Windows hater until Windows 7 came along. It was quite acceptable. Windows 10 is even a little bit better. Just roll with the punches.
The DOS versions I liked the most were 3.3 and 6.2, though I remember DOS as far back as 1.1.
Reminds me of a song "Those were the days my friend, we thought they'd never end......"
