If you want to go quickly and have a comfortable position on the drops and a more aero position for a headwind get a road bike. You can get ones which have a more relaxed geometry.

I started on a hybrid, found my hands hurt on flat bars, converted it to drop bars, and eventually got a road bike. The road bike was about £200 more than the hybrid but feels MUCH better, it is quicker, has better components, more comfortable etc.

So from experience I'd say go and take a decent test ride with both styles and go for the one you enjoy.

For me, owning both bikes has been a huge experience - lots of maintenance practise from upgrading my hybrid and now I'm slowly starting to realise what style of bike I want (turns out it two: a cyclocross with disc brakes, and a fixed gear road bike!).
