PC Magazine's March issue pitted Mac OS X 10.5.1 against Windows XP, Vista, and Ubuntu Linux 7.10 in every imaginable category, price, installation, interface, security and more. Leopard won four of the eight categories and was the overall winner.

Leopard won the installation, interface, bundled software and security categories. Ubuntu Linux won on price. Windows XP won the third party software, drivers, and networking categories. Vista didn't win in any of the categories.

PC Magazine concluded: "Mac OS X 10.5.1 is the product to pick for our mythical average user who wants something secure, easy to install, and easy to master. That you can run Windows and Ubuntu on today's Intel-based Macs -- enabling you to use all these OSs on the same PC -- is just gravy."

In the final tally, Leopard received a 4 out of 5 rating, XP SP2 3.5, Ubuntu 3.5 and Vista 3 out of 5.
