I'm glad you're happy with Windows.
Pulse Audio was released 13 years ago. I haven't heard of any issues over 5 years. Gnome 3 was released in 2011 (there were widely used alternatives). If you go by Linus, who swore off Gnome since 2003, he switched back to Gnome in 2013 saying "has been getting less painful" and "things are better than a year ago."
I'm not going to defend every part of systemd, or even that it was a net win, but I don't think it was a frivolous change, either. Starting and stopping services asynchronously has obvious wins (as well as obvious pitfalls). Personally, I would hit problems where the user's environment would bleed into the services they started and stopped.
Other than systemd, the changes you mentioned are well behind us. All of them had alternatives and distros set up around avoiding them.
