If your needs are fairly typical, Android is fine—on a phone. On a tablet, most of the apps look like blown-up phone apps. On iPad, that sometimes happens, but it’s rare. Developers actually make an effort. As for Chunky, that’ll never come to Android. There are reasonably good alternatives for Android (ComiCat was what I used to recommend, but I note it’s not been updated in three years; Astonishing and CDisplayEx get a lot of love and are… fine), but none I like to the same extent. (The app I really hoped would happen was the Chunky follow-up, designed to pull libraries from remote storage. Seemed ideal for me; but development appears to have stalled.)
Aspect-wise, comics fill the iPad display in landscape/DPS, but in portrait will find black borders left and right—although that never bugs me because that’s where my thumbs sit. For wider usage, I prefer the squarer format, though. I find it more useful for work-related tasks (writing; spreadsheets) and creativity (painting; music creation)—and Apple’s ecosystem has the apps for that. (Android has some apps, but they are fewer in number and generally not as good.)
Reviews won’t be biased in the manner you’re concerned about. No reputable website will be nudged by Samsung to any degree. The only issue with Samsung is that, in my experience, the loan periods are annoyingly brief. So there’s always a kind of shorthand in reviews. (You get a week, mostly, with their hardware.) The unit does compare favourably to iPad in some ways, and if in areas that matter to you, go for it. Just tread a bit carefully.
