Why so critical of "universal" flex radiator hoses?

I remember those Family-First days like they were yesterday. Oh wait, it was yesterday! In today's topsy-turvy world, they never really end. My 68 is languishing in the carport, cuz I give all my spare money to the 3 little Beggars I fathered. Hyup, it's still Family-First.
If I don't drive her this summer, it will be the third no-drive summer. She's needing body work pretty bad.

thats the point i got to, where "its time to redo this car right" Its been torn down for a few years, but its worth it when you see that its coming together, and the body is straightening out,

If your fixing on running your wife and kids around in that old hotrod you'd better make sure you don't install the parts most likely to fail

I never had issues with the flex hose, in fact, this post points more to aesthetics and concourse "correct" issues rather than functionality. I did read about "flow problems" can't say I ever experienced them. I suppose my point is, one can spend a lot of $$$ making their car correct, or get it on the road and drive it.. Whichever side you take , in the end one person will be working on their car, while the other will be out driving around in it. You start with the correct hose, then you put a worm clamp on it, and some "expert" will call you out because it isn't a "correct" radiator hose clamp, then you get the clamp, and another "expert" will call you out because the hose has Gates or Dayco stamped on it in ink, not Mopar, and so it never ends,and anyone can play that game if so inclined. Will I replace my flex hose? most likely, is it a show stopper if I want to drive my car? absolutely not.
