Yeah, they're OK for me. Many Plasticville structures from Bachman in the '50's are postwar survivors if they have not been glued or otherwise altered. For those of us that have a similar nostalgic attachment for them as we also have for our Postwar trains, they are a must on a layout.
Beyond that, they are reasonably priced if found at a show, and can't be beat if you want to kitbash them. The other newer highly detailed structures that are already weathered are much nicer looking, however, you get what you pay for, and you will pay a lot more for them.
