IMHO - hard to breakdown because you can not discount the LIC's when there was only one division ('63 - '85) and also teams that have switched and won in two divisions (SWR - MAN)
here is my all time programs - I give the best program to GC because they had a tougher time getting out of Nassau then WM did in Suffolk untill the past 15 years
#1) GC 15 LIC's
#2) WM 17 LIC's
#3) Man 13 LIC's
#4) WI 8 LIC's
#5) SWR 6 LIC's
