I always use the Europass format. For an IT sysadmin job, it's not like I'm trying to prove that I know how to use a basic word processor. Or demonstrate the type of artistic design skills that go into coming up with my own format. I like the fact that by using something standard, I'm less likely to be judged on stuff like choice of font etc. It tends to cover key details in a fairly terse format well which at least leaves scope for more wordy explanations in a cover letter. I find I don't end up needing to tweak the CV much when adapting it for different job applications while any cover letter does tend to then be fully one-off.

That said, my record in actually ever landing a new job is fairly woeful but that may be more down to being poor in interviews.
