Every lens manufacturer has their own "look" or "signature" characteristics. These go beyond specifications. If comparing "sharpness", lenses like the S1 are exceptional. The S1 lenses are typically very heavy, but well constructed. You really cannot go wrong with them.
My personal third-party axe of choice has been the Tokina AT-X series. I had owned a 35-70/2.8 which I really, really liked. I mistakenly sold it during a spate of "Zuiko Only" years. These days, I have a full bag of Zuiko optics, but I have a Tokina AT-X 100-300/F4 lurking in there.
I've bought and sold a few Soligars through the years. Every single one suffered from horrible Chromatic Aberration.
These days, other than the Tokina, I'm firmly in the "Zuiko Camp". I particularily love the "look" that Zuikos give me. My pictures just look different than what other people get. But then, I'm also rather particular about the generation of lenses too. Other than a 24/2.8 and a soon to arrive 35-80/2.8, all of my lenses are silvernosed.
