If you're painting them white anyway, and don't mind cutting MDF (you should wear a mask) then I prefer MDF. I just find it easier for the reasons above, but some people don't like it because it's not real timber - each to their own of course.
It's relatively simple to DIY skirting, the hardest part is the corners as robj20 said but if you get a cheap mitre box to help it's a lot easier. You can also hide a multitude of sins with your filler of choice.
