Is presentation of work more important than the work itself?

I think you're right. People are really more happy with a good presentation than with a good work! I think it's so important because nowadays people judge don't have time to read works and so they need to see good presentations that economize than time!!!! But I think work needs to more important in some areas. Or equal!!! But people really apreciate more the good presentation for a bad work than bad presentation to a good work!!!

I think it depends on who's viewing it. If you know the things that are presented, you will notice if the presenter knows his/her subject and whether they've done a good job or not. Of course, a bad presentation doesn't help much if they haven't done a good job, but I don't think a good presentation can save you if you for example have done a really bad job on a school or research project.
