I'm a BIG fan of partitions. The work exactly as Big John designed them all those years ago. They shed weight to transfer energy, yet retain at least 60% of their weight for penetration. I load them in all my rifles, except my wife's (only because they wouldn't shoot well enough at the velocity she needed for recoil management). If your rifle likes them, I think you'll be pleased by their on game performance.
That said, you're starting from scratch, don't have a preference, AND can afford a box of each, I say let your rifle choose. From what I read of Barnes, they'll do exactly what you want, so long as the rifle likes them.
