Betamax was arguably better.

Not in ways that the market cared about.

Arguably better quality, but at the cost of being shorter. In the great trade off of time, size, and quality, I think VHS chose a better combination.

It depends which definition of "better" you use. VHS won the adoption race, so it was better there. While Betamax may have been technologically superior, in hindsight we can say it apparently failed to address other key aspects of the technology adoption lifecycle.
