It is userspace - meaning: you have to log in first before you have consoles. I fins it very comfortable on Linux, to have syslog output sent to tty12. So no matter what happens, I can simply switch to tty12 and see what's going on internally in my computer. That will not be possible that easy in userspace.
It runs on top of VT220 - meaning: Once you send a control sequence that screws up the VT220 completely (so that you have to chance to type "reset" any more) you are out of luck. In my time working on Linux, I have had quite a number of consoles screwed up, but I have never ever been in a situation that console switching was not possible any more (unless, of course, the computer was completely dead) I do not believe that one will ever get a single console with userspace VTs as reliable as the Linux VTs are.
