All classes can perform as a healer. If you didn't like the druid (heal over time based), maybe you should try a paladin for mostly direct heals, which is the most diametrically opposite kind of healer to a druid. Personally, I really enjoy my tree healer, as rejuvenation, regrowth and wild growth heal over time spells suits my play style.
Try level all four healing classes up to lvl 25-30 and heal with them in dungeons, and make your decision based on your experiences. They all get more and stronger spells later, but it will give you an indication of differences.

Maybe you should check out the "Bored Druid Thread" in the Druid forums?
