I'm in the same boat. I've used both Macs and PCs for years and I find the Mac's shortcuts to be easier to remember and, overall, more useful than the PC's. PrintScreen to capture the whole desktop is nice and easy, but anything outside of that is a pain in the ass. I love that Cmd+Shift+4 lets me select an area of the screen with 1 hand. I'd be hard-pressed to remember, much less find, if Windows has suddenly added that capability and, even if it did, you'd have to use 1 hand for modifiers and one hand for PrintScreen. Macs have always had it so it's muscle memory now. If Windows added it, it was recent and requires 2 hands.

Most of the time on Windows you want full screen (PrtScrn) or a single window (Alt+PrtScrn). Windows definitely wins here vs Apple's Cmd+Shift+3 and Cmd+Shift+4, with the additional modifier to copy to clipboard instead of save to desktop.

On the other hand, Apple's accent input (old style, not the new style that stops key repetition grrr) is vastly superior than alt codes. Yeish.

Windows has had the Snipping Tool since Windows Vista. Print screen is obsolete though it still does work. Snipping Tool is really great, you can even make a free form snip.

Any combination of modifier keys excluding the 'menu' key will combine with PrtScn with one hand under Windows - all the modifier keys are available on the same side of the keyboard as PrtScn on a standard keyboard.
