ASRock IPMI, at least on X570D4U Ryzen 5000, is unusable. You can't turn on the firewall allow only specific IPs, it blocks everything. They said they have a beta firmware (> 01.39.00) to solve this, but it doesn't. Had to purchase a Spyder to add to the machine.
Supermicro's BMC UI on X11 does feel like 2004, but it is decently reliable. On the H13 series is even more stable and doesn't feel outdated.
