If you are referring to 9/6 Double Double Bonus Poker; the expected return (ER) is 98.98% but the variance is 41.98; which makes it a risky game.

Some games are have a postive ER; but you always have to weigh the variance of a given game (since the higher the variance the higher the volatility).

That being said, Loose Deuces Wild has a Variance of 70.70 and a ER of 100.15%; but a much safer game is 8/5 Bonus Poker with an ER of 99.17% and a variance of 20.90.

Probably the biggest complaint is finding the full pay machines in the denomination that you want on the strip --- but, in all cases, the ER on the worst video poker is much much better than slots (which can have an ER in the low 80% range) -- that is why the casinos give you fewer comps for VP play (in comparison to reel slot play).

Of course, the above VP numbers assume you are playing perfectly, which folks seldom do --- especially with some of the more esoteric games.

My suggestion would be to learn one strategy well (like 9/6 JoB which works well for 8/5 BP) and stick to that; and learn to identify the good full pay machines (which are often right next to the short pay (bad) machines).
