Difficult to estimate. From my visual perspective, it seemed that initially the grizzly was closer to our point of view, but then the polar bear ran closer towards the camera.

When people need to debate about how the camera influences perceptions, we can be sure that the difference cannot be that great.

One of those videos is the one that got discussed here all the time and the other has no relevant fighting actions (we only see the beginning of the battle).

Retreat? One of those videos showed a grizzly bear roaring and a polar bear backing down a bit (not necessarily fleeing). We don't know if it counterattacked or not.

There was one polar bear that stepped back slightly (proving nothing), in each of the two videos, when a grizzly rushed in its direction (certainly not from its mere scent). You don't have the slightest clue as to what happened after the 3 seconds you actually saw, and yet your entire argument about grizzly superiority is based on them. And I've already posted a video showing a black bear retreat from a vastly larger grizzly only after a full-out fight, only after letting the grizzly approach without showing any fear at its sound or scent.

I find the idea of a polar bear fleeing from a smaller bear merely from its scent to be rather dubious. Granted, grizzlies are pound for pound the strongest and most aggressive bears on the planet, but to intimidate a polar bears on scent alone would require some serious domination in interspecific conflicts.

45kg is a signifigant size advantage for any wild predator to have over another, I'd back a black bear with that weight advantadge over a brown bear, it would at least dominate the fight.
Another thing is that while brown bears may be more impressive on a one to one basis, black bears aren't pushovers either:
Macropredation:
"Because there are no records of black bear preying on adult elk in the literature, the following observations of a single adult killing two mature, male elk on the same or successive days at the same spot are worth recording."
"Bear biologist Martin Obbard, at the Ontario Ministry of Natural Resources in Peterborough, Ont., stresses that predatory attacks by black bears are rare. Still, he says, "Bears do kill things. In Chapleau, a male black bear killed a moose cow. That was pretty impressive: he weighed about 340 lb. and the moose was about 800"
Serious interspecific altercations:
"A large bear killed and ate a mother and two cubs at a
den in the upper peninsula of Michigan in mid-April 1963
(D. Wenzel, unpublished report on file at the Michigan
Department of Natural Resources Headquarters at Crystal
Falls, Michigan)."
"a 5-year-old
radio-collared male was dug out of its den and fatally wounded by another
bear in Alberta in mid-October 1976 (Teitje, Pelchat, and Ruff,
personal communication, 1982)."

Bottom line... a mature male grizzly will have no fear what-so-ever of a larger black bear. But, if you disagree, show me a black bear standing his ground against even a grizzly she-bear or even a juvenile grizzly.... I'm waiting. I know this is an old quote, but still: Black bear and grizzly share a steer carcass: Black bear chases juvenile Grizzly from kill (13:25-14:10):

Even with the advantage of weight, latter still wins.

I favor the black bear, it has the size advantage needed to win. At parity I would favor the brown bear though
