what's after the rebirth series?

I’ve collected all the rebirth comics to the series I like. I don’t know where to go from here now hahaha

I always go back to the Silver Age comics when I am up to speed with the latest. They are wholesome reads. Each issue often has the enjoyment of a full story. The villains are more fun, they were as crazy as the imagination of the writer.

Well, which series? Recommendations are easiest with more info.
