I want to buy a sony HX5V, will the pictures excell compared to W380?

Everytime I want to get a camera I look to get a better picture than my last camera. My recent purchase was W380 but today I'm considering buying a Sony HX5V but the sony shop said no you better buy a Sony NEX5 but I have a Nikon D200 so that is probably as good as the NEX5 and the Sony HX5V is smaller to carry. I want to achieve beautiful travel pictures mostly shot close of people and sea etc. Please advise me, Will the Sony HX5V be sharper pics than my Sony W380

Added (1). I liked P's response, but I have the TZ8 and I found Fuji cameras to sweat and get sun damage in places like Egypt. However I'm still very interested in the Fuji idea and will follow this with more research and also I have read very good feedback now about Nex5V

Panasonic zs10 and fuji f550 are probably the best of the new superzoom, superspeed compacts.

The Sony NEX5 gets excellent reviews. My daughter-in-law has one and loves it. I think the Sony shop gave you good advice.
