I agree. You want to buy the bike that fits you best; the only way to do that is to test ride them.
As an example, my wife had it narrowed down to a Giant Escape 1W and a Specialized Vita last spring when we bought her a new bike. She was leaning towards the Specialized because she liked the colors (black and pink), but then she rode them both. We ended up walking out the door with the Giant because it fit her better and she was a lot more comfortable on it.
