Are all (cheap) headers created equally?

I've been doing a lot of reading about headers, because I'll be needing a pair.
It seems like every pair under $200.00 is exactly the same! The Hooker appear a bit different, but from what I read, but they have installation issues as well. So does it REALLY matter? The steel thickness is the same, they are all painted black, they all have a 3" collector, and the all have fitment issues!

If this is the case, why not just get the cheapest out there? Summit brand for $105.00.

Please correct me if I'm wrong.

Thanks!
