I really enjoy batman by snyder and batman/superman by pak and im just wondering if detective comics has gotten better with the new writer, is it on par with these books?

It's still not on par with them, but it's a lot better than it was.

Last issue was surprisingly good but before that it was trash

I thought the Emperor Penguin arc wasn't too bad but I'd probably still say start with issue #22.

I liked the Emperor Penguin arc. The newest arc with the new villain Wrath is very excellent so far but still not quite on par with Batman.

I'm haven't read Batman/Superman but its better than Snyder's Batman IMO.

The Emperor Penguin arc was really cool and Detective Comics is way better than Snyder's Batman but it ain't on par with Batman/Superman.

Start with emperor penguin, the only problem was some editorial interference because of Death of the Family and the Requiem issue. Layman is really growing as a Batman writer with each issue and Fabok is a very good artist.

I agree with @queencorp15: Last issue was good. I'd recommend it.
