I'm going to sound a bit out of character here but for me none of them really stick out and grab me. I don't dislike any of them, but none of them make me excited either.
I really enjoyed all the GW1 G&G maps, but there Cactus Canyon is still my favorite to this day, especially the last part where zombies push the giant golf ball.
In GW2, I found both zombie attacking maps (Seeds of Time and Great White North) to be less enjoyable than the 3 plant attacking maps, and I especially love Zombopolis, that map's visual alone made it a joy to play, even if the last stage could be iffy.
Here, they all work and after they adjusted the drill in Goopy Gully, they all play pretty well, but none of them wow me or make me groan. Once we get some new ones, and hopefully soon, I hope we get some really exciting ones.
