It's worth it.
I put one in a few years ago amd the car rarely goes upto 1/2 way on the temp gauge, usually stays between 1/4 and 1/2.
The downfall is, on the cold winter days, 30* and below, it takes longer for the car to get warm, but living in the Middle East, I don't think you have to worry too much abut cold temps.
I run the a/c all the way out to Lansing and it stays between 1/4 and 1/2 and it's usually about high 80's low 90's, also in the summer traffic running the a/c it gets to 1/2, but usually not over it
