I originally bought a Red, but after reading through their web site, i decided that the Yellow would probably be better due to the deep cycle and because they say it's better suited for vehicles with lots of electronic draw. It did cost me a little more and it's only got a 1 year replacement vs. the 3 year on the Red, but it's piece of mind and i like that 
Also, i don't know if it's just me, but i think my car revs quicker with the Yellow vs. the Red, but that's probably all in my head.
