I've never painted with Blender. it might be killer don't know.I don't use Blender much I play with it from time to time but that's about it. I don't have a decoder ring ;)

I still box model with a old version of C4D 9. one day it wount work on a the new OS .Then I'll have to get a new box modeler or just use zBrush.yes you can now box model with Z.

If Blender has a zBrush spot light it's cool for texturing.

never tried it but 3DCoat was popular.A lot use Photoshop it has a 3D painter in it like zBrush I think. probably more brush settings.

Substance Painter is killer with maps n ya paint all the texture, spectral, normal etc etc at same time.

my best guess would be Substance Painter,Photoshop.are best for texturing.I haven't tried every 2D app there is ,but played with a lot of them.
