Wouxun is not quality. I may be a good hobby radio, but they are a far cry from a good Motorola or Kenwood. You can get UHF Kenwood mobiles with Part 95 certification for well less than the $319 they want for it. But the skill required to program a Kenwood or Motorola isn't there for many GMRS users. Nothing wrong with that, just different radios for different uses.
They do fill a role, though. They are easy radios to get into GMRS with, and fill the needs of 99% of the users.
