Why would someone choose to play at Sweepstakes Casinos with Sweeps Coins redemption instead of just using Offshore Real Money Casinos?

I see people recommending social casinos all the time. I get that they are technically legal in most states, but the redemption process seems complicated compared to just depositing crypto at an offshore site.

Is this preference purely about the legal safety, or do the sweepstakes models actually have better RTP on their slots than the offshore guys?
