So far I've only really tried Komik.
I like the simplicity of it, no cluttering, no unnecessary options. But it is slow to load pages, especially when CBR file is a 100+ pages (15-20MB)
Also, sensitivity of the touch to turn pages or access page list is too strict, too often it thinks one wants to swipe-turn pages, so one has to tap several times to get the right tap and turn the page.
Finally, seems like it won't display GIF files in CBR even though the list view of thumb pages will display properly.
Would be nice too to be able to choose which cover comes as main cover in the "shelf" view, maybe by reading a specific image file at the root of each directory?
