DC is the old school control system. Straight from the transformer to the tracks. DCC involves radio controlled receivers that serve more like realistic cab controls on locomotives.

Personally, since I’m on a limited budget, I stayed with DC. It all boils down to preference. I really wouldn’t justify the expense of converting my locomotive roster to DCC.
By the way. I’ve been working on the 3rd incarnation of my LJ&S so don’t feel overwhelmed. I used to have a ’64 Plymouth fury as a project car but had to get rid of it due to health concerns.
