Hello Carlosa, I'm sorry but i find the ZBrush UI weird, this is mainly why i try to avoid it as much a possible,i would love 3DCoat to keep a good distance from it. Mudbox have a nice UI, i love the 3D coat UI too. The 3DCoat sliders are handy since it save a lot of space. This is just my taste.
i think the problem with the sliders in 3dcoat is, that you dont see the lower end and the upper end. So you cannot see your relative setup point. Here is Mudbox better IMO. But the orientation of the Text is better in 3DC (3dc <-> Mudbox). 3dc text-layout seems to be more sober, not so flattered or turbulent, when comparing the two pics.
Although a little more graphics do not disturb.
BUT NOT AS zBRUSH! It is too stressy, no relaxing for the eyes
