Yes, it's awful compared to KB&M.
The camera is all over the place and never really as I want it, a certain hag's cavern full of gas traps was a nightmare to navigate... the camera was jumping up, down, to the sides, terrible.
In combat as well, 90% of my gameplay is fiddling with camera angle and distance, my god, it's awful.
Radial menus are OK, but you have to spend time to actually set them up how you want. I did it and I'm now happy how it works.
Also not a fan of having to make 2-5 button presses in order to switch party members...
