that's like saying VHS vs betamax is subjective. VHS won but wasn't better. Or Minidiscs vs CD's. It's mostly due to marketing fails and people hopping onto marketing bandwagons and pre-estalbished products.
TS is more popular due to combination of google dropping the ball in defining the standards and getting others onboard with them cause they overestimated the leverage they have, failure at marketing it and how everyone is already bought into Javascript.
I'm glad to see passionate developers keeping on both sides. That's how we grow and become better.
