The question is simple. Regardless of manufacturer and material, which setup do you prefer?
The question is too simple. It depends on the game!
The game I play most often is Texas Holdem, so my answer is jumbo.
For games with more than four hole cards (including non-poker games), I prefer standard.
For games with exactly four hole cards, it depends which game. If there's a board (like Omaha), I prefer Jumbo. If there's no board (like Badugi), I prefer standard.
And I always prefer poker sized over bridge sized.
Bridge-sized makes an end-riffle easier, which is what a lot of players do, but I was trained as a dealer, and do an edge-riffle, which is easier with poker-sized.
Poker-sized always feels better in my hand, too. I suspect that people handling bridge-sized cards roll the deck more often, but cover cards take care of that.
