Paint colors

Nobody around here sells Tamiya paint cans, only Testors. So I have a few questions...

Which is better, Testors spray cans or Tamiya paint airbrushed?

Also, are the colors matched? Like is Tamiya red the same as Testors red?

I use Tamiya paints through the airbrush, and must say I love it!
Great texture, it does what it says on the tin, and if it all goes wrong you can remove it with oven cleaner!
Primer the parts first, takes away any scratch marks!
