4 of a Kind
I’ve played in hundreds of games with two decks and have hosted hundred games with one deck. Two decks never work out smoothly. People passing around piles of cards..
Almost all games I play have two decks and there is no comparison to single deck games. @TexRex is right. If the next deck is ready for dealing when the last pot is pushed it saves that shuffling time, every time. The only way time is liot is if shuffling a hand distracts action. I think that's possible in shorter games, say 5 or fewer players
But my experience does not share the notion that it is only good in theory. It plays faster.

, there is no downside to using a button in a self-dealt game.
