Welcome to the forum and we're looking forward to you becoming a contributing member after a basic learning period. Biab and RB will do everything you want and much more but it does sound like from the tone of your questions you've never done digital audio recording before? Have you worked with one of the big name DAW's? DAE = Digital Audio Workstation. Real Band is a DAW. Biab is sort of a DAW but not really. Both can do notation and can print out charts but consider the full version of Finale costs more than both Biab and RB combined not counting the cost of all the Real Tracks and Drums. That means Finale does much more in the way of notation and chart writing than either of these programs can do. The question is does Biab and RB do enough to satisfy you? I don't know the answer to that but for most of us that answer is a qualified yes. Realize though notation and chart writing are not these programs primary purpose. The primary purpose is exactly what you're asking about. Creating some really good jam tracks to basically any song you want for you to play with, write solos to, all that kind of thing. You have complete control over repeats, first/second endings, coda's, tag endings etc. There's so much control that Biab is pretty complex when you want to dig in to these things. But, to just get started it's pretty simple to pick a style, enter the chords from either your head or a written chart and hit play. It's all the cool details after you've done that is where the program really shines but it will take some time for you to get familiar with it.

Nothing is perfect, there will be a few things you'll wish it could do better but overall there's nothing even close to what these programs can do. They really are unique and you won't be disappointed.
