Uber being more mainstream has nothing to do with quality comparison.

Even so, tell me again which is actually the crappy toilet paper in this comparison...

I use Lyft primarily because of the grossly offensive scandals surrounding Uber, I'm talking even from the early days when execs were caught bragging about threatening journalists, to sex abuse, to lying to everyone about their 6 blown red lights in a single week during self driving AI testing in SF. The services do the same thing, almost exactly; Uber's track record might as well be the deciding factor.
