It all depends on what you want to do. I love my bard, many think bards are a waste of time till they play along with one. I also love my hero, after a long day at work its sometimes nice to come home and slay things with a really big sword. They all have there strong and weak points.
Think about what will make you happy and read up on them all. Its like trying on a new coat, what might look good on the rack may not hang right once you have it on. Roll something play with it for a day or two, you can always delete and try another.
