Since most aircraft don't have oxygen, the question is rather pointless.

You can carry oxygen on board easily enough. It seems prudent to me to
always
have oxygen on board, but that's just me.

Sounds to me like you need oxygen just to fly your desk. It's useless to the
vast majority of GA flights.


If an aircraft does have oxygen, it most likely has the capability
of easily clearing mountains and the choice is obvious.

If the choice were obvious, I wouldn't ask.

The choice is extremely obvious to most any experienced pilot, and this is a
pilots forum.
