Shameless plug for the Fun Bus here, it's $22 cash. I go 2-3 times per year, play the minimums in Blackjack and Craps and still get free hotel offers, $15 - $30 in free play, Comp credits, etc. So in terms of your question, Montego Bay is where I win, mainly because it's where the Fun Bus drops off! If you want to be a winner in Wendover take advantage of their generous comp program. Their Craps is great too, 10X odds on any point and 12 pays Triple in the field, which I have never seen anywhere else (it makes the house edge lower on the field bet than placing the 5 or 9). On the weekend the tables are usually pretty full so it keeps the play slow and the dealers need to shuffle every two hands so you won't get wiped out blasting through 10 hands in 5 minutes if you're at a table by yourself with a shoe. Plenty of single deck Blackjack that pays 3-2 with $5 minimum all day and night including weekends. Having gambled plenty of other places ( Vegas, Connecticut, California) this place is a gamber's paradise.

That being said all three offer the same games, odds, payouts, etc. They renovated a while back, it looks great and everything looks fresh. I have only been to the big three (Montego Bay, Peppermill and Rainbow) and they are all nice, but I prefer the Montego Bay.
