The form factor is quite different as is, so I would definitely prefer both, ideally anyway. The current MacBook Pro chassis is arguably not big enough (or designed well enough) to make use of the high end processors in it. It is amazing how well they do when you look at the size of PC laptops with 6 or 8 core CPUs in them—but the idea that the iPad can do everything that a high end laptop can do just doesn’t make sense. If you want to compare a MacBook, MacBook Air or similar, there’s absolutely a point to be made however. And I’m not sure how long customers will be okay having features not accessible to them on their ~$1K iPad Pro that exist on their ~$1K MacBook Air. If Apple were to be brave here they could potentially make a big leap beyond Microsoft and their sorta compromised “PC as a tablet” that’s found in the Surface. But if Apple drags their feet then the Surface could really make the iPad look like a horribly hobbled device with the potential to be so much more.
