FanDuel vs DraftKings vs BetMGM which sportsbook should I actually pick and stick with?

Every time I look at these three, it feels like I’m back at the roulette wheel, chasing a small edge that only sometimes matters in the end. I like a clean interface and fast withdrawals since I tend to cash out rather than roll everything forward blame it on my love of counting chips. Been sticking mostly to single game bets and a couple parlays on weekends, nothing wild, but I like a book that doesn’t mess around when I actually win. Bonuses and promos seem nice at signup but honestly, half the time I forget to use them before they expire.

Is it better to stay loyal to one spot for any real perks long-term, or is it smarter to move around depending on the lines and promos? Anyone here actually notice a difference when it comes to day-to-day betting or is it all just window dressing at the end of the day?
