eero Pro 6E v.s. TP-Link Archer A7 - eviltoast

I have an Archer A7 at home and I have no issues with. We also use a single TP-Link AC750 WiFi Extender for a part of the house that otherwise has a weaker signal.

Recently, we started using Frontier for fiber and they gave us a free eero Pro 6E. Now, I have a choice to either:
a) sell the eero Pro 6E on ebay (can get around $100)
b) replace the Archer A7 with the eero Pro 6E

I am figuring the “cost” of eero is essentially what I can get for it if I sold it, so my question is: Does the eero Pro 6E do anything better than the Archer A7 that would be worth $100 to upgrade?
