Refined doesn't mean better. It means "distilled". As in all frivolous things have been removed except the most important core functions.

And even If Amuro had a true Zeta Gundam, he wouldn't do any better. If both pilots are equal, than a Zeta Gundam is not beating the Sazabi. If both pilots are equal, then A Zeta Gundam isn't beating a Jagd Doga either.

CCA era suits completely outclass Zeta era suits. As seen when Char humiliated Amuro when he was using the Custom Dijeh.
