Advice on 'Upgrading' Existing ASUS setup

[zedmo]

Currently have the following setup

Asus RT-AC2600 as main router

ASUS RT-AC56U as 2nd router (connected to main via ethernet) in bedroom at other corner of the house
All rooms have ethernet access points.
I switch between 2 access points depending on where i am in the home.

Have the following lying around and wondering if it's worth changing to.

ASUS RT-AC87U

ASUS Lyra Home

ASUS EAN66

I'm afraid most, if not all, are already End of Life:

I would thus prioritize based on maximum bandwidth...
