I find tiling more efficient because
- I can have predetermined layouts per desktop where my often used programs are.
- I only have to purposely move windows out of the way if I've made the floating on purpose, and
- Less mouse use and more keyboard use for changing the layout, resizing windows, changing to another window ...
The more I use tiling, the more advantages I find. At this point I think I could use any desktop as long as I had Krohnkite functioning tiling.
