I use 2 laptops, both with linux (ZorinOS) and windows 10 LTSC. I also run 1 or 2 Windows OSes inside VMs.
I use windows for programs I can't run in linux, and I don't do any private browsing on them including entering passwords.
I use the linux OS for browsing and portable browsing (moving around the house)
One machine has random mac, so it leaves no wifi foot print. The other doesn't so it stays wired with wifi disabled.
When I need use the web I switch to linux. If I have to brows AND use windows apps, I either use 2 machines, or I run windows in VM without internet.
It depends on usecase.
