Whats the Best OS?

First and best OS i used was Linux back in working at Computer Repair shop in 2012 before windows came out and Linux gives you more ability do lot more then MAC and Windows but thing you might thinking is Windows and MAC OS are basses as Linux but all coded in BIOS firmware's. so for me i would say Windows 10 most best then linux since you can run Ubuntu inside Windows using SUB-OS packages and Install Ubuntu by Windows store. other that i used dual boot OS but win 10 more backwards OS inside windows 10.

and linux i use was Ubuntu, Redhat and Cent OS 6/7 keep you reminded.
