As two others implied, really apples and oranges. Chet was the quintessential representative of theWest coast sound, and Miles (and Dizzy) was the leader of the East coast sound in the 50's. The two schools of jazz are so different they really stand on their own.
BTW, Miles started on the West coast and actually played on stage with Chet. Look for album "Miles Davis and the Lighthouse All-stars" from 1953 in Hermosa Beach.
Also, Chet was always very respectful of Miles, while Miles denigrated Chet. Miles publicly saying that Chet ripped off his sound, as strange as that sounds....
