Worthwhile to count 1 deck 6:5 or 6 decks 3:2?

Given that most single deck games in Vegas now are 6:5 BJ payoff, what are the opinions about playing a single deck with a(any) +/- counting system at 6:5 versus 6 decks with 3:2? My thoughts are that even with the 6:5, I still am better off because the frequency of favorable betting situations would be much higher with single deck and assuming a 5x-10x betting spread, still yield a higher return than the 6 decks at 3:2. Thoughts?

You'll only get 2 hands per shuffle in a single deck game. If it's dealt face down, then you wont have any extra info to help you at all on the first hand. You'll have the chance to have a nice advantage in the second hand, but if BJ is only 6:5 in the single deck game then I think you're better with the 6 deck game.

You are better off with a 6 deck game. The whole point of card counting is to give you a better shot at blackjack. If the blackjack doesn't pay you will lose the advantage.
