Should I finish reading the end of New 52 Superman before diving in to Rebirth?

I read through the first trade of Yang and Romita JR’s run on Superman nearing the end of The New 52 and while good, from what I can tell it doesn’t really have any significance going forward into rebirth, so should I finish this or start reading rebirth now?

I know about the whole N52 and Post crisis superman meeting and like combining together thing in DC Rebirth, but I think that’s really the most major thing I need to know going in right?
