I know they both have some different uses but overall which one do you like better ?
What advantages and disadvantages do you see of the one you pick or both of them.
It's a bit of a loaded question, because I got to use both at work last year, and boy did I hate the HP Elite windows tablet that the school procured for us. Being so thin meant poor battery life, and bad thermals. The device constantly throttled, and excessive zooming resulted in numerous cases of screen burning out (because the processor was so close to the display) amongst my colleagues. Likewise, the form factor was pretty awkward. The detachable keyboard meant it was essentially a laptop with a broken hinge, making it awkward to carry around (I had to cradle it on my arm like a baby). The UI was generally quite unoptimised for touch and well, windows is still windows, with all its idiosyncrasies.
Another issue with enterprise devices is the general lack of software support (I remember having to open pdfs in Microsoft Edge just to be able to annotate on them).
In contrast, my iPad Pro had better battery life, portability, cellular connectivity, and I used the apps on it more (scanner pro, notability, camera, screen mirroring, lumafusion, just to name a few). I had airplay mirroring on my Apple TV years before my school finally invested in Miracast dongles for the laptops.
I can't get all my work done on an iPad (still need a PC for a lot of the stuff that I do as a teacher), but the reality is that my school laptop stays docked at my workstation to an external monitor and I often just go to class with my iPad (amongst other stuff). If I really had to choose, it would be a laptop but it would be a crappy experience indeed.
