From what I've read on here, most of the (cheaper) aftermarket radiators for our car are visually identical to one another as they're direct fit. Aside from the Mishimoto radiator cap possibly being leaky, has anyone had any issues with Koyo or Megan radiators?
Go with koyo. You won't regret it. Mishimoto and Megan are just cheap copies.

Related question: Is the Honda coolant causing what looks like severe corrosion around the radiator cap? Or does that just wipe off?

With all due respect, the Mishimoto radiator that I got for someone installed flawlessly, it was $289 shipped which was the same cost as the Koyo. QA improves with time even in China.

If they're the same price then there's absolutely no reason to buy anything other than koyo lol

That green and white gunk is dried coolant. It'll wipe off. Any coolant will do that if leaking out of the radiator.
