Home Assistant Green Smart Hub vs Aqara Hub M3

Hi all,
I was wondering if I should still get the Home Assistant Green Smart Hub when I have the Google Nest Mini Hub for controlling my smart devices? Contemplating getting the Aqara Hub M3 but want to make sure it works with HA Hub?

Wondering if you should buy apples when you have pears already?

What is HA Hub? More like cherries or raspberries?
