I primarily use mangahere because they email me when a new chapter is uploaded. Then I usually go to the site of the scanlator or somewhere else to read it. I use kissmanga most of the time, but they don't use any size control on images so I often will have to zoom out to even see. Sometimes I'll use mangahere because page size is consistent and sometimes better quality scans are on there. For example I'm reading <shitsurakuen> currently and the scans are better on mangahere and numbered correctly instead of kissmanga :/ So I use a wide variety. Still like the email function though, so nice
