This will be heavily biased by region and time period. Most local announcers are not heard on a regular basis outside their markets. The legends are legends because they called the game for long periods of time(20+ years) during the heyday of radio.
Today I enjoy Jon Miller's calls on both TV and radio.
As a kid Russ Hodges and Lon Simmons called a great game for the Giants. Bill King used to call for the A's. But I cannot compare them to others like Red Barber, Harry Carey or any of the other immortals because I never heard them regularly.
