I use this Satechi adapter which I got for around $20 at Microcenter, and it works perfectly and is a good fit against my MBP.

I personally like that I can use it on either side of my MBP. Same with charging. Many times I use it in tight spaces, so instead of dealing with static ports and a charging port on just one side (which leads to dealing with cords that get in the way), I get some flexibility. May not mean much to most, but it was a surprise pro coming from a 2015 MBP.
