Being that both are heroes, the "best" outcome would be a scenario where the most lives are saved at the least cost (as a major example).
You could personally like a "worse" ending, but that doesn't keep it from not being the "best" ending.
Here's a hard example:
One thing you could argue is what if Paragons save the galaxy but lose humanity as a species while the Renegades lose all other races even.. but humanity survives. Technically, Paragons have the better ending (with more lives saved) but some may personally prefer that Humanity pulls through.
You are using a paragon definition of 'best.' Given that, it is not surprising you insist that the paragon result is best. Renegades tend to be pickier as to who they want to survive, for instance, an ending where humanity is strongest, or where Shepard ends up in the best situation personally.
The example you are using is a good one.
The thing is, Shepard is not neccessarily purely a hero. Renegades are usually better defined as 'anti-heroes.'
As I said, it is you picking premises that suit your arguement.
