Kind of depends which generation of servers. I had worked with a lot of x9 and x10 (xeon e-2600v1-4) which was alright, as long as you don't mind outdated java (well the newest x10 bmcs do html5 consoles too, IIRC); but I recently started renting an x8 server personally, and it's worse... My favorite is when serial over lan just stops responding when you go from console redirection to os opened serial port (and back)... real helpful for inputting disk encryption passphrases. Oh well, I'm renting this server because it's cheap, it's also 10+ years old, and it works enough.
