IMO, go to the one closest to you. Saves you money on travel and maybe even lodging.
Since I'm about 35 miles from Baltimore I've been to the Whitman Show 10+ times. I've never been to a FUN show but I'd like to go once just to say I've been. Same with the Central States Show. But I'll stay east of the Mississippi. (Also went to an ANA show in New Orleans once.)
Describe it as if there were no picture. Picture it as if there were no description.
However, I've been to Baltimore as both a collector and dealer so I can speak there. Baltimore attracts a lot of attention and is structured numismatic chaos. But if you want a coin I promise whatever you're looking for is there. Whether that be a $50 coin or $500,000 one. I enjoyed Baltimore both occasions and was able to secure some amazing coins. The benefit of either is prices. Many dealers will sell for 10-20% off of their eBay prices at shows. One such example is my bust half. Priced at $1300 on eBay I secured it for $1050 in person.
