I'm using UberPOV mostly for the things specific to it so haven't really
compared until now.

Checking on that I found good news and bad news. The bad first.
Shadows from area light looks like jitter is always on even though that keyword
is left out.
The good news is it can be very fast.

More bad news, because even when attempting to equal the shadow appearances (and
they won't for whatever reason unknown to me) the subsurface scattering gets
worse not better. This with everything the same other than changing area_light
adaptive. Can only guess SSS requires more sampling when adaptive is increased,
just not tried yet.

Sorry Jim, for not starting a new topic. Will do so here in image group to show
the comparison.

Bob
