need help choosing a new catalytic converter

here is the problem guys...
i cant bolt on my new header to my cat because the previous owner of the car replaced the cat with a universal fit one, not a direct bolt on
and i rather bolt it on because its eaiser to take out and it wont void the warranty for the header either, so im forced to find a direct bolt cat and then buy a catback and change the whole exhaust system at the same time

right now im just looking for a new cat first, honda charges 700, but im going to get an aftermarket instead...
no high flows or test pipes for me, so ive come down to these 3, but i dont know which brand to go with...

i honestly trust the first site more because...well...
it costs more, and i guess im hoping that it will be a better quality than the others, lol
so what do you guys think?
i want something that will last
