Load regulation is generally tight, especially at 12V, the rail that matters the most!

Ripple suppression is good in most rails but not competitive since the competition is crazy in this section. In any case, below 35mV ripple at 12V under full load and above 47C is a pretty good performance. Only the 3,3V rail needs improvement here.
