alternative to high compression, forged, and stock pistons?
 

is there any other type of piston that is better than the above listed?

Depending on the application they make different shapes on top of the piston, domed is the one I've most commonly heard of... as far as better I think it all depends on application

how about a naturally aspirated motor

For a naturally aspirated motor you'd want a domed piston. For a motor seeing boost you'd want a dished piston. Most motors come with cast pistons from the factory. Almost all aftermarket pistons are forged.

domed vs. dished is mostly to adjust the compression ratio. Domed = higher compression = good for NA. Dished = low CR = good for boost.
