It's not just a title. The committee has to decide on agenda and other aspects in some consensus reflecting the parliament, ensuring that minorities are heard at that level. Where the committee doesn't find agreement on procedure they got to make a vote by full parliament, which distracts from actual work. Regarding Germany, which I know better than EU: Also mind that the parliament is self-governing and the vice presidents deal with a ton of adminsitrative tasks. From parliament police (Bundestagspolizei) to building construction and maintenance and employment of Parliament staff. Not forgetting representative tasks, like visiting opening sessions of parliaments in other countries etc. and then the actual work in leading the debates and on the side also policy work. It's serious work.
