MasterAni been my favorite lately, they also cover some Chinese animations like King's Avatar.
I use crunchyroll from time to time, but of course they don't cover every show, since many different business been jumping in to own rights to stream em :P
Edit: MasterAni is not a legal source, but at least they aren't littering the site with ads to fund themselves.
i totally agree!. just gotta becareful of the dam popups lol but ya, 9anime, and watchcartoononline.io are what i use. if your computer savy enough to maneuver "no script" as a browser add on, it can be a life saver when watching anime online as far as avoiding pop ups goes.
