Best To Go For Text-to-speech Feature Or High-sensitivity Receiver With A Garmin Gps?

I’m narrowing down my search of which GPS I want to get. Now I’m stuck between two, one which has the high-sensitivity receiver feature, but not text-to-speech, and the other, vice versa. Which is more important? Does the high-sensitivity feature really make that much of a difference? Thanks in advance!
