If you own Bob Dancer sponsored software, I think it has to be either WinPoker or Video Poker for Winners. VPFW is excellent, WinPoker was excellent when it came out years ago, but it hasn't been updated since forever. But either one would probably suit your needs, so if you still have either, I'd try them before spending money on anything else.
I don't have any experience with it, but people I respect say that Wolf Video Poker is excellent. And you can get a free copy of Frugal Video Poker from Wolf.
But for someone with an iPhone or Android, I'd consider buying WinPoker on the iPhone or VP Pocket on Android. They are more limited than the software above, but for me, portability and touchscreen manipulation makes it a lot easier to use.
And I'm not sure about the other software, but if you have Video Poker for Winners on an old PC, you can transfer the software at no cost to your newer PC.
