Great post! I may come back to edit this and expand on my thoughts, but quickly:
Peachy District is my clear favourite. It has an end stage with a lot of tactical decisions to make. The colourful urban environments make a change from the brown that dominates some other maps. Spawn points are not too far from objectives. Not too linear, and few choke points - attackers can come from multiple directions. Every base can go either way, there are no cakewalk stages. And I love the cut scene when zombies win.
I don’t like push-the-payload stages, and I don’t like being spawned miles from the objective, so Loggy Acres is not my favourite map. However, after the zombies cakewalk the payload to the electrical station, then things get interesting. I have enjoyed some epic battles capturing or defending that base. Bomb delivery is quite frustrating. As @GammaX6 said, you’re on your own most of the time. I prefer to accompany someone carrying a bomb and provide covering fire, since I figure that’s more helpful than trying to walk the bomb across the map all by myself. But I think plants have it worse. Even if you put up a solid defence, it tends to unravel one the zombies deliver the first bomb, I guess due to time extensions providing a big advantage.
I dislike the end stage of Turning Point. On the surface it seems similar to Loggy Acres (bomb delivery), but it is more frustrating for both attackers and defenders due to the pickup and drop off points being switched. It is no fun to throw yourself in front of three or more engineers turrets trying to pick up a battery! And for attackers it is no fun to chase down a captured battery as a plant carries it back to their base.
There are no maps that I won’t play, and I never switch teams.
