There are still many Vegas casinos where you get 3/2 odds on blackjack and play with a six deck shoe. Don’t give business to the strip CSM and 6/5 games if you don’t like it.
There's still single and double deck blackjack too. Treasure Island on the strip has double deck and a lot of casinos on Fremont, with El Cortez being my favorite, has single deck. Both are 3/2.
In Vegas in 2021, I was surprised to see double or even (rarely) single 0 roulette tables mostly empty, right next to full triple-0 tables with the same min bet. Players seemed to understand the game too, so I guess the better table had just opened up and they didn't feel like moving.
