6-deck vs. 8-deck w/ better pen

A local casino has fairly generous penetration, giving a decently playable game for a casual redchipper like me. No matter how many decks they're using, they always deal down to about one deck left, sometimes even a few cards deeper.

Is it worth playing the eight-decker to get the better relative penetration (88-90%) over the six-deck game (83-85%)? Everything else is the same between the two tables (H17, DAS, LS).
