Depends on many things such as age, price, time of day, etc. In order:
Cohiba (too pricy though)
JL#2 (best value for my taste)
PSD#4 (smoked more than any other)
RASS (usually needs the most age to shine 3+ years min)
ERDM Choix Supreme (when I want less ligero but plenty of flavor)
Technically Edmundo and Trini Coloniales are not robustos but both are close.
