Alright, I'll bite. I can't comment on "favorite" without stepping on toes...but all mentioned so far are good picks. Doc (RIP), Bill Treanor, Wah, Yak, all aces. Beef gets points for being fun to listen to and to chuckle at. Mark Mianulli, #281 (RIP) was always a comfort on the radio. Ted Byers, mister TWO TWO TWO. Though only a dispatcher briefly in the 90s, I was always partial to Joe DiBernardo #356. He went on to R-3 and was involved in the Black Sunday incident. Bill Hahn # 106 also is pretty good.
Let's not forget some of the new kids on the job who are aces... Jeff F #244 in the Bronx comes to mind, also Eddie O in M.
It would be a telling survey to see who was your LEAST favorite dispatcher...
It's always an interesting question to ponder about what makes a "favorite" dispatcher...it's kind of like a DJ on a radio station. It's a combination of personality, unique delivery, speaking style, and of course, knowing your sh*t!
