Nate,
I cannot comment on the iPad Pro as I do not have one; but I have used the original iPads and other tablets. I do have an iMac, MacBook Pro and a MacBook Air (slightly older versions). Interestingly enough, all three have slight nuances in their use but I have found them to be excellent for the choices I've made.
If you're looking for portability without the stylus or touch screen interface, then I'd say the Macbook Pro or Air would be a great choice. The Air being lighter would get my vote; the Air will compromise overall storage compared to the MacBook Pro.
I'm "old school" and still prefer keyboard/mouse/touchpad interfaces. The Air does not have a CD/DVD Rom drive so depending on what you plan, you may need to pick up a USB version. But if you're good with digital format on all of that, then you'll find more storage accordingly in the Air over the iPad version. The downside, is that the Pro/Air will require "unfolding" where the iPad is a bit more nimble in handling.
I think it's a "Your mileage may vary" type of question and it really starts with your intended use.
Happy hunting.
