I do era/release and members - age order (and usually separate the group/set cards). I also tend to separate my bias unless I have duplicates then i put them in too.
I do by group, then by member, then by album (most recent at front). Only one group per page. For example, in my binder, I have 8 ATEEZ pages, the Hongjoong page is first in the group, and from front to back i have one from gh pt. 4, gh pt 3, and gh pt 1.
I have each binder separated out by album release. So each album my group releases gets its own dedicated binder. Within that, because I am OT8 and collect all the card sets I can, I separate out the PCs by the sets they are in.
I generally go by era, with seasons greetings, md cards etc in between depending on when they happened. But for cards with an era I go by the order of album card then pob/fansign then md/popup!
