I recently got an Air after using a MBP13.
Aside from the loud fan and slow performance which should be fixed in this release, my biggest complaint is that they only have the usbc plugs on one side of the laptop.
Really obnoxious when the outlet is in a difficult spot.
Unclear whether the new MBP13 also has this problem...
Edit: the new M1 MBP13 has both usbc ports on the same side. No option for 4 (yet). Ugh.
