JSA: Morrison or Young justice: David

Hi there, I’m fairly new to DC side of comics and been reading through some! I’ve read through the early start of Batman’s career (year one all the way through killing joke) and started reading some of the iconic Superman stories

Anyways I was planning on picking up the omnibus for one of these series and was just curious between these 2 which would be better as a newer reader? I don’t really have character preferences for a series, more interested in reading good stories that won’t leave me confused and having to read a bunch of outside material to understand. Both seem very interesting and I know are highly regarded. Any input would be appreciated, thanks!
