Since this is just an option question, I dislike "great stuff" I've
had much better results with the latex competitor. The stuff doesn't
over expand, and cleans off clothes.

I think you are talking about the DAP product. I've used both. The DAP latex
material is a little softer and less dense than Great Stuff. Depending on what
you plan to put on top of the foam (if anything), Great Stuff provides a
slightly stronger base for material like plastic wood.
