I live in Michigan. I tested 4 apps over the weekend, Barstool, Draftkings, Fan duel and MGM.
What I found was Fanduel to me had the best interface, draftkings the best boosts, MGM gave away 100 free dollars, and barstool has some “unique promotions.
Going forward I will probably keep FD for the easiness of use, and DK for the boosts (saw -100 on any team to score a TD in the Superbowl next weekend) Barstool I may bring back for the occasional fun bet and will probably ditch MGM altogether. Does anyone else have preferences into what they use?
