It depends how you *exactly* formulate the question. Fully hardened and up-to-date instance of Windows vs Linux? An average instance as given out to a regular irresponsible user? Desktop? Server? Mobile? These comparisons without specific context are idiotic and nothing more than a popular dick contest.
As for Android, it certainly has much better application confinement than typical Linux deb/rpm apps, Linux only catches up with Snaps/Flatpak/systemd now.
