Why were you looking for a replacement/upgrade? Is your HA Green failing, or is it just too slow?

Asking as someone who is considering purchasing one (just to run HA on it, obviously).

I kinda just outgrew it.

I migrated from Homey to HA, and with 2500+ entities across some 250-300 devices the HA Green performed well. It would sit at about 55% RAM usage with 5-7% CPU load, so in no way resource strained.

My storage however was not exactly doing well. I frequently hit 80% or more storage used (of the 32GB eMMC). The HA Green uses USB2 and has no connectors for adding more storage like the M.2 slot on the HA Yellow, so there was no easy upgrade path.

Compute wise and RAM wise the device did well. I ran HA, Mosquito, ESPHome Device Builder, Matter Server, OpenThread Border Router, Piper, Speech to Phrase and a couple other add-ons, and besides the speech stuff it worked well and responded fast to almost everything.

Speech in any other language than English is slow at best. English is a little better, but don't expect to have long conversations with it in realtime. For my use case, of making one way announcements, it didn't matter much if it spent 3 or 30 seconds preparing the announcement, it would arrive when it arrived.

The HA Green lives on in my summerhouse which has around 900 entities and maybe 50 devices. It works well there, sits at 2% CPU, 39% RAM, and 45% storage, so I guess it depends on the "size" of your installation.

At home I'm monitoring "all the things", EV stats, EV Charger stats, heat pump stats, TRVs, smart electricity meter, room level presence detection (Bluetooth LE), mmWave presence detection, Smart Switches, Smart TVs, Apple TVs, Sonos Speakers, everything. I also have around 100 automations dealing with various house states, like when the heat pump and EV charger both kick in at full power, an automation will tell the EV charger to chill a bit before it blows the main fuse, and once the heat pump finishes its cycle, ramp up the EV charger again.

The summerhouse, on account of being smaller, naturally has less stuff going on. It's a place for relaxation, and most automations and sensors there are targeted at detecting stuff when we're not around like water leaks, temperature drops, heating anomalies, motion detection by the cameras, etc.
