I agree that they are underrated.
I too must be the exception to the rule on the looks part... I really like the looks of the Rugers ... at least the P93, P94, and P97. I do not care much for the P85/89, P90, P91, or p95.
The ergonomics are a bit better on the P93, P94, and P97 than the P85/89, P90, P91, P95 due to the use of curved as apposed to straight sided grips ("reversed palm swells" is the only way I can explain what I am trying to describe). This makes the P93, P94, and P97 a bit less 2X2-ish or brick-like. Still though, the CZs and the Sigs feel better in my hand. But I do not shoot the CZ or the Sig any better.
Ruger DA triggers: The Rugers I own or have owned have relatively long and heavy double action triggers much like the Beretta 92. But, in my experience, they are very smooth, some almost buttery smooth. Because they are smooth I have found them easier to keep on target throughout the trigger stroke than a CZ or Sig. I find them to be heavier than the CZ or Sig triggers but easier to keep on target since the CZ and Sig DA triggers seem to be stagy to me.
Ruger SA triggers: Are hit or miss. I have one that is better than any CZ I have tried and is almost as good as the best Sig that I have tried. But, in general, they tend to have a gritty glitch in them prior to reaching a point where there is a smooth break.
I owned a Sig P220 and the Ruger P97DC. I still have the P97 because I shoot it better than I did the P220.
