Talstar P and Bifen IT are essentially the same product, they are just made by different manufacturers. Talstar P was manufactured 1st and is known to be the "name brand" and Bifen IT is known to be the generic. Onslaught is micro-encapsulated and will last a little longer on outdoor surfaces which does give it a bit of advantage over Talstar P or Bifen IT. You can also use either one to do a barrier treatment around the outside of your home and in your crawl space to stop pests from moving indoors.
