>>2593If you have an android device I'd recommend installing Tachiyomi and getting MRM, batoto, and mangadex as sources. You can put sadpanda on there too but I can't remember how easy it is to use. Basically you can go to browse and search all your source sites in one go for a title and check which has the most chapters uploaded, instead of copypasting the title into multiple site searches.
On the scanlation side of things: mangadex gives uploaders full control of their chapters including replacing individual pages when you need to fix things, bato.to is apparently quite amicable when contacted to fix things but you have to communicate with people.
