For a particular riding use, you're going to get the best results from boards designed for that use.
I like Lib boards and for me they work good all-mountain. NOTE- I said "for me" because it really comes down to subjective preferences for each person.
For me the Banana I would say is more park oriented. Where if you went to a C2 profile it is more versatile between park and off-piste. Although it won't stand up to a free-ride designed board for off-piste use.
I haven't tried all the boards, but from all that I have tried for free ride I like the Jones Flagship and Rossignol XV; depending on the conditions and qualities of the snow.
Good luck in your quest, as I'm sure you'll get 100's of opinions. The best I can say is to demo as many different boards as you can and even rent for a day different board profiles. Find what works for you and also remember that what works great for you today is subjective to be different next month.
