Online Training or classroom based?

Could anyone give me their views on whether I should do online courses or classroom based. Any experiences you could share would be welcome. I could do the full MCSE online but only a couple of MCPs on classroom based with my training budget.
I have the motivation to do either but how practical is it to do online training in a lunch hour when eating lunch at your desk doesn’t stop people coming over with problems? Also, has anyone done a course with SmartCertify and if so, what did you think?There are no right or wrong answers here so i’ll share the points.
