Why so critical of "universal" flex radiator hoses?

Flex radiator hose is the automotive version of going WalMart in pajamas and fuzzy slippers.

Reminds me of a story I never shared before. The previous owner of one of my Mopar project cars asked me if it was OK to drive down to the DMV with me as he was dressed at that moment (pajamas). I said it was all the same to me, so off we went, me fully dressed and this other guy in pajamas. Never understood the why of it.
