I'm a big fan of budget alternatives, and these foams will work just fine.

One caveat:
Alot of memory foams are open-cell. As the name suggests, open cell foams are porous. If you cram lots of it in your doors, and the window seal is displaced by a few microns... you'll get water in your doors. This water will soak into the foam and stay there. Not only would that be heavy, it could get moldy.

That's the reason most sites advertise closed cell foam as the best way to isolate rattling panels.
