The table above tells you, for each viewer application, the overall verdict of Win or Fail; whether it opens multiple Gerber files, if it opens zip files; whether it opens and displays drill files properly; UI quality; richness of feature set; and additional notes.
Some of the problems listed above might be fixable but I could only spend so much time on each product. My top picks are: GerberLogix, gerbv, and GC-Prevue.
GerberLogix is my favorite Gerber viewer. Easy to use, simple and clean UI, simple zip import, and fast to launch and load. Update: Version 2.5 now automatically detects Excellon format so the drill file displays perfectly.
Gerbv comes in a close second favorite. If only it opened zip files it would be awesome. It is also fully featured, displays correctly and doesn't appear to have commercial use restrictions. Since I'm now selling products, I'll use gerbv as my go-to viewer. It's also Linux compatible.
GC-Prevue is fast, you can import multiple Gerber files or zip files, and it has a lot of features including the ability to merge Gerber files graphically!
