Slots are just randomness, there is no skill involved which isn't appealing to me.
I'm a stats guy and much prefer table games as they can be skill based. For instance, If you know how to play poker or blackjack properly or know what the best bets are in craps, you can heavily cut down the odds and sometimes put the odds in your favor. Over the long run, factoring in player reward comps like food, rooms, shows, etc, it's pretty much free entertainment.
Not all table games are skill based however. Stay away from roulette for example, yet even that game has half the house edge of penny slots.
Fun fact: Did you know that nearly all penny slots do not let you bet a penny? I think I saw one in Niagara Falls where the minimum bet was 50 lines, or 50 cents a spin. Max bet was like $5 a spin
