do crypto casinos have better odds than regular online casinos?

Been comparing crypto casinos and traditional online ones, mostly looking at RTP numbers and whether provably fair tech actually changes things for real players. I know some games, especially dice and crash, claim you can verify every result, but most of the slots just run off the usual providers under the hood, so I'm not sure it makes much difference.

I do see more aggressive promos in crypto casinos and sometimes the minimum house edge is advertised as being lower. But once you move past the splashy new player offers, is the RTP on slots and table games actually better? I've checked a few crash games where the edge is clear, but for roulette, blackjack, and the majority of slots, it seems like the core math is almost identical to what you get in the regular online spots. Curious how others are seeing this.
