Choosing right shader (Patreon)

alShader - very easy to setup, correct, but to long to render and noisy result.
VRaySkinMtl - hard to setup, not correct, as you can see in examples in attachments it have no red bleeding where it needed, no idea what is wrong, maybe it's me doing something not right, or another bug in vrayforc4d. Anyway, it is very fast to render.
VRay FastSSS2 - not so hard to setup, not so correct, too much bleeding where it not needed, this is possible to fix with hand painted masks for problematic areas. 30% slower to render then VRaySkinMtl, no idea why, probably another bug in vrayforc4d, still waiting for servise release with bug fixes and new features, for more then six months now...
I think I will stay with old good VRay FastSSS2.
