OSCP - VM Update Question

I've read both arguments for using the OS-provided Kali VM specifically made for the PWK coursework, as well as using the most current and patchex Kali builds.
Not sure there is a consensus, as OS says to use the specially built one, and some reviewers have claimed to have issues performing some tasks due to deprecation and what not.
However, for anyone who has recently gone through PWK, which did you use? Any advice? Did you apt update the PWK VM at all, or just add in specific tools you found you needed?

You can always keep a backup copy of original VM on disk.
For the labs I switched to an up-to-date "real" Kali, which I'm still using to date.
