I use kde for my main desktop. Although I will probably switch to a window manager when I get the time to learn it.
I tried gnome once because I thought it was better for laptops (I used asahi for a little while on my macbook) Although I quickly changed to kde because I could not live with the horrible window tiling (only half and half no quarters) I realise now you can probably fix this with extentions but I didn't get around to it.
