so what do you think is the best guitar neck shape,fretboard radius and scale lenght for playing all kind of chords?
Far too subjective for a meaningful discussion. Although most players who primarily do chording like a more rounded fingerboard radius.

I also have to do that. Cottaging this weekend
I've found the flatter fretboard to be much better for everything since I've started to use the classical posture.

As far as scale length goes, I believe that if playing chords on 25.5" is harder than on 24.75", then you need to work more on correcting your posture and technique.
Guitar comfort is not in any way objectifiable. Not sure why that's so hard to understand.
