I like the bus stop too, but it doesn't look good anywhere in my town. It's also always weirded me out because why does a small closed-off town need a bus? Is it a tour bus? Where else can it go? Does it go over the train-tracks? Everything's walking distance. I guess I could imagine it's one of those small mini buses, or those open cars used in safari tours.
My favourite pwp are the solar panel and the geyser. I had a geyser but destroyed it because it was made this massive dirt spot, and my grass still hasn't recovered. I'm trying to think of a place to put it, but it'll probably end up going near to where it originally was.
I also love all of the pwps you can interact with, or that makes a sound - so pwps like the wind turbine, water pump, bell, climbing frame, and the cube sculpture.
