I mainly read digital comics.

I currently own a Nexus 10, which is 5 years old, has a battery that dies suddenly and struggles to work if I'm ever connected to WiFi.

I'm looking to upgrade, but not sure if I should go for Windows or Android.

I've used ComicRack, Komik, and Perfect Viewer, all to some success. I haven't used anything on my Windows desktop to read, so not sure how great the program options are.

Any suggestions for what might be the better option?
