All of you are wrong aside from OP
Efren revolutionized 9-ball. He stomped over everyone like King Kong until they figured out how to kick safe. Efren was so good at escaping what were considered "captain hook" safes, absolute lockup safes, it just blew everyone away. Excellent cueball, excellent pace, and he followed the Al Davis mantra "Just win, baby, win". He snatched victory so many times that we can't even count.
Most of the guys you mentioned in the vintage trifecta used "hit and hope" as a real strategy. Even when they figured out how to play, he was the undisputed master of creative play and ferocious defense for 20 years.
GOAT for sure. All modern play is based on his style.
