We may actually be seeing the moment where Moom[1] is no longer an essential OS X app. It can solve both window tiling and the "maximize problem" on mac and has been my first install for many years. Here's to hoping that Apple can get one basic OS feature right once.
The 'cycle' option in Rectangle.app allows just this. I use the hotkey(s) + bracket keys to cycle 1/3, 1/2, 2/3 screen windows justified left or right, and the hotkey + pipe key to cycle center justified.
These three shortcuts are embarrassingly effective and cover 99% of my window tiling. Others include the standard hotkey(s) + return for fullscreen and hotkey(s) + backspace for the previous window size..
