Much more power. I used an Air, on principle, for way too long. A very old Air at that. It was stupid of me. I got a beefy late-2015 MPB, the last model with the ports, and it was life changing. I then tried a 2016 (I think) new style MBP and it was even better. It was as light as my old air, but with the MBP specs. Liked it, but it was just a loaner so I had to return it.
