Why can't we have both? I mean I do not gamble too much on regular games but when it comes to NBA playoffs times I do gamble a bit so I do like sportsbooks however during the regular season and specially during summer I do play on casinos a lot.
Having both will give us bigger chance to win but that only if we have luck
But if we don't know about our luck, then picking only one will be enough, so we don't have to be greedy to expect to win the game. I prefer to use the casino to play online gambling because I don't know how to place the bets in the Sportsbet.
