MBA vs MBP

I use a MPB M3 Pro for work as a designer with no issues, great rig.

Starting a business so I don't want to use my work computer, looking at:

MPB M4 pro 14/20 core

or

MBA M4 10/10 core

Will be doing medium duty Illustrator, light photoshop, possibly very light instagram or social video editing + emails/etc.

Would it be worth $1K more for MBP and an added 1" of screen?

thx in advance
