Let's face it: if you can afford to play the higher limit slot and video poker games you are going to get the better paybacks, the better paytables, and the better odds of winning.
This is true for table games, too. At a $5 blackjack table you might find that a blackjack pays 6/5 while at a $100 table a blackjack pays 3/2.
It's a well known fact that higher limit slot machines have a lower "hold" for the house. Penny slots might seem cheap to play, but the "casino hold" on penny slots is much, much higher than on $1 slots. So this means if you are betting 100 coins on a penny slot you'd get a better return just playing a $1 slot.
And it is true for video poker, too. Harrah's Rincon has the traditional full-pay 8/5 pay table on many of its Bonus Poker machines from 25-cents per coin to $10 per coin, and that's good. But if you want a better deal, the high limit section has Bonus Poker with the payoffs adjusted on the quads that boosts the 8/5 pay table from the full pay 99.2% to a very attractive 99.66-percent. But to play that pay table you'll have to play Rincon's $25/coin and $100/coin machines.
See my report on this unusual pay table for Bonus Poker on the "Video Poker News and Commentary" page at this link: http://alanbestbuys.com/id132.html
As I wrote in the article, Rincon calls this game "Bonus Poker." But does it have a different name elsewhere? Here's a shot of the paytable on the $100 machine.
