I can’t tell if you guys are serious.

But my take on CatBus’ original statement is that he was stating something that’s pretty subjective (an opinion on the ranking of bear sub-species) and making an outright qualitative statement and saying it as if it were fact.

And he was saying it in a slightly mocking but mostly jovial way, trying to draw a parallel to your argument. CatBus may enjoy black bears. Maybe he likes the grace and power they display. But that doesn’t make them unequivocally the ‘best’.
Someone else might appreciate te regalness (regality?) of a polar bear. Or the grace of a brown bear. Or the ferocity of a grizzly bear. Or the comedy of a panda bear (which may or may not count as an actual bear).
But none of them can be right, absolutely, that the bear they like is truly the ‘best’.

Similarly, one might like the detail of d+77, or the grain of 4k77.
But there’s no definite/absolute ‘best’, so probably best not to argue about it.
Especially in this thread.

Also CatBus was wrong about one thing. Panda’s are clearly the best bears.
