Ground Strap vs. Ground Cable

So I recall something about using ground straps instead of ground cables. Can someone enlighten me as to why the straps are better to use instead of a large gauge cable (which I am currently using).

Another member on another post mentioned that ground wires work on surface area. So a thick round ground cable is not as good as a large flat ground strap, if I understand it correctly.

Just to be certain I replaced my flimsy rotting frayed ground strap with a 0 gauge ground cable. I also just got an inch wide flat braided cable to put on the firewall to the cylinder head. I will probably go over kill and add a few more from the battery to the radiator support as well as the fender to the cylnder head near the MSD box I am installing.

I recall my dad's challenger had grounding issues and he added about four flat woven ground cables from cylnder heads to firewall, and block to fenderwell and it solved the problem.
