No, many of my colleagues do this, using desktops. They use the four finger swap left/right to switch between the different fullscreen apps. It's their main multitasking method.

I think it's partly because alt + tab does not exist on Mac. Command + tab is between applications rather than windows. Command + ~ is between windows within an application. I had to downloaded HyperSwitch to get the same functionality.

edit: HyperSwitch is free. HyperDock is what I paid for.
