While I’m not a fan of most the names they used on Earth 11 I do tend to prefer the character designs. Although some like Carol Jordan and Hal Ferris were just all around bad.

I just read the issue with the first one today, Teen Titans Spotlight #11. It was published post-Crisis, but set earlier. I'm not sure how that's supposed to work with the multiverse never having existed after Crisis.

It's basically post-apocalyptic Tintin, and I always thought the genderswap Earths were pretty lame, so that gets my vote.

The current Earth 11 has Teen Justice, so I reckon that gets my vote.

For some reason I thought they were Earth 16, but that's definitely a point in the Multiversity Earth 11's favour.

In my personal headcanon, the Black Condor of Earth-11's real name is Lance Dinah.
