The one that works best for you. I know that is not an answer that you were looking for, but the deal is that different people have different results with the various radios that are available. If you are happy with your phone, signal strength, GPS lock results then you should probably stick with what you have for now. Or, you can test out the newer radios that are out there and see if it improves any of those things. Probably the best answer you will get outside of lots of conflicting personal testimony. Good luck.
