If you choose the machine on the right, you'll lose your money six times faster!  And your chances of winning will be far less.  If the reason isn't obvious then consider this:  If the player is getting back 99.54% and 97.29%, that means the casino is keeping 0.46% and 2.71%.  The casino profit on the second machine is 2.71 ÷ 0.46 = 5.9 times higher.
The best video poker machines, played skillfully, offer odds that rival any table game. The basic game, Jacks or Better, in its full-pay version returns 99.5 percent with optimal play over the long haul. Other machines, especially some versions of Deuces Wild, offer a positive expectation to the player -- that is, over the long haul, they'll return more than 100 percent with optimal play.
In order to pay for the increased pays for four of a kind hands, other pays have to be lowered. In Bonus Poker pays for the full house and flush are reduced to eight for one and five for one from nine for one and six for one respectively on the full pay Jacks or Better game. This makes the return from the “full pay” version of this game 99.17 percent. This is certainly not as good as a full pay Jacks or Better, but it is still not bad. 

A straight is a hand with consecutive ranks, like 9? 7? 10? 8? 6?.  Notice again that the cards don't have to appear in order.  The order of face cards, from lowest to highest, is Jack, Queen, King, Ace, which we abbreviate J, Q, K, A.  An ace can also count as 1, to complete a straight where the other cards are 2, 3, 4, and 5.  But it can't count as both a low and a high card, e.g., Q K A 2 3.
