I tried out the Trek hybrids during the course of choosing my current bike. My riding style is "city trekking" -- I'm not comfortable on road bikes because they don't feel nimble enough to me, and I don't need the features of a higher-end mountain bike. But I couldn't find a hybrid that fit (standard or WSD). So I went to a mountain bike (the Trek 4500), had the dealer put hybrid handlebars on, and I installed the Easy Seat saddle myself. So now I have a hybridized mountain bike that is very comfortable to ride, and thus is great for fitness as well as fun and safety (well, as much safety as one can find on the streets of Memphis).
So make sure you road-test whatever bikes interest you, and make sure the fit is right -- both for your body and your style of riding.
