What makes it the best os? Even without telemetry, it has a huge memory and CPU footprint from a bunch of bloat services running, restricts/blocks functionality even from admin users, and is very inflexible. The only thing that kept me having a windows partition was gaming - but now a vast majority of games (and other software without official Linux support) can be played with wine/proton. My PC idles at 0%-2% CPU usage and about 6 GB of ram, and basically all of that ram comes from me self hosting a good number of docker containers. And even that aside, windows collects data from a lot more than just the telemetry option
