I briefly tried Freeze-12. Didn't seem any different than R134a to me.
I tend to use Duracool. The only downside I have is that Duracool seems
to find it easier to escape from the system. When it is properly
charged, it cools GREAT (as good as the original R-12.)

Note: Duracool isn't legal in all US states. Where it is legal you must
first have converted the system to R-134a fittings and oil (per US
Federal laws).
