I'll put my vote in for DipTrace.
I'm definitely a hobbyist level user. I send out a board at most 1 time per 3 months. I wanted a program that was easy to learn and return to. I had used Protel many years ago.
I feel DipTrace has a reasonable price point for a light user as well as a reasonable upgrade path if/when your use becomes heavier. I bought it at the Starter level (300 pins, 2 signal layers).
I like to have my designs stored wherever I like and the software developed for the current OS, so I feel I can comfortably continue to use the software, even if the company goes out of business. I didn't want board physical size restrictions. Once again, though, I'm a hobbyist with respect to PCB's, so the software doesn't represent my livelihood.
I can't comment on the quality of the copper pour for a heavy user or more than 2 layer capabilities. I typically use the autorouter with perhaps a few nets hand routed beforehand, finishing with a copper pour for ground, say. I'm not trying to have the program control impedances or define net classes; no power user here.
I tried Eagle & KiCad and found them too awkward for a casual user. DipTrace hit the sweet spot for me. I can make symbols, footprints, schematics, and PCB's with either a quick tutorial or the old copy/paste from existing, similar parts. I send my boards out to Oshpark and have never had an issue with the process or the results.
