Just got the 500 Mbps upgrade this morning and now I am looking for equipment upgrade..

Current setup:
Ground floor:
- Main router TP Link Archer C2
- Wireless AC speed up to 433 Mbps
- 4 Gigabit LAN ports
- TP-LINK TL-WPA4530 KIT AV500 Powerline ac Wi-Fi Kit  (LAN endpoint 100Mbps connected to main router Archer C2)

First Floor:
- TP-LINK TL-WPA4530 KIT AV500 Powerline ac Wi-Fi Kit  (wireless endpoint)
- Wireless AC speed up to 433 Mbps but capped at 100Mbps because of the LAN port is only 100mbps.

What router did you guys use that can utilize the 500mbps via wifi and the coverage is strong enough to upper floor (3 bars and above)?

I am looking at this currently but looking for opinion too:
TP-LINK Deco M5 AC1300
