Hypotheticals aside, because you'll never find one of each that is in the same condition with the same instruments and the same trailer.

Therefore, the nicer one is the one with less wear and tear on the interior and exterior. Total Time doesn't matter. It's how it's been taking care of.

The better one is the one with newer instruments and the nicer trailer.

And the best one is the one that comes up for sale that you can afford.

2 real cents from looking at a lot of gliders until finally buying one.
