Sports betting became legal in Arizona last year, so I’m relatively new to is also, TH, and I’ve settled on three books that I use daily. Who gets my bet depends on the odds offered, boosts offered, etc., for said bet. Odds difference between the three is sometimes significant.
In order of preference…..
DraftKings - good layout, easy to read, good Search function, offers daily boosts in all leagues(mostly for parlays), odds are always competitive
MGM - offers a fair amount of boosts and free bets, odds are competitive, layout is decent, more difficult to read after latest update, laggy
FanDuel - quite often offers the best odds between the three, daily offers 1-3 boosts for specific parlays(some are gimme’s, some not), layout sucks(takes a while to figure out where certain wagers are for an event)
I tried the Caesars app but I didn’t care for the layout, too difficult to “read” , too “busy”.
Props for getting prepared. Find out which book/books you will be using and determine which signing bonus will benefit you the most. Good luck!
