I use HoneyView
, on Windows and Linux (via wine, works fine mostly, unless you use Enter and browse in the selection window through the images in the archive). I've tried supposedly better solutions, like MangaMeeya, but HVs slickness, minimalistic not-cluttered UI and just-works^TM keeps me with it.
It's worth to mention open source QComicBook
, but it's no way near the competition, and UX isn't as good as it should to gain users. I have to praise it for implementing panel-navigation algorithm for instance (sure, it's not perfect, but it's a really hard thing to do right).
I'm still thinking about doing my own cross-platform (Qt) minimalistic viewer for PDFs (and images in folders/archives as a second priority feature). Well, Okular+HoneyView are almost good enough, so I always postpone starting it, and there are always more important things to do... :)
