I've had versions 1, 2 and 3. Haven't gone for 4 yet.

Gave up trying to do anything that has any interactivity. It's a bit too slow for desktop use, unusable for 4k HTPC and while retro gaming worked ok, Parsec didn't work as well as I thought it should.

As a low powered server though it works reasonably well. Pihole is very reliable especially blocking ads on phones/iPads in the house. I'm experimenting to setup the pi as a VPN gateway for the house as well as a low end NAS/cloud backup gateway.

Good luck

Thanks but I've decided to leave my rpi3 as a pihole/ssh server for now
Even with the rpi4 there's no AES hardware acceleration so VPN will be slow especially for me with a fast link
