I haven’t tried any of those honestly. My previous setup was just a Raspberry Pi running docker with portainer GUI, and nginx pointing to one service. It took me at least a month of dealing with errors, and I got burned out when I could never get geo-blocking or fail2ban working.
I stumbled across Cosmos when the dev posted about 0.16 release and the main draw for me was integrated reverse proxy, geo-blocking, anti-bot/ddos, and automatic updates. I have only run into a few hiccups setting it up and the discord is pretty active so my issues had either been solved before or someone answered me quick

Now that I bought different hardware for the cosmos server and my Pi is free I should check out proxmox and unraid though just to compare
