As far as I can tell after 2 years of playing the only class that is unanymously disliked in my group is the Fighter Champion. The adjectives vary from useless, to boring, but ... yeah other than that I have never heard a complaint from my group. Plenty on the forums though but I think my gamers aren't very power gamey so they don't crunch math.
As a GM I think the most baddass build I have seen is a Human Barbarian (using feat start variant) with Greater Weapon Master and a 2 handed great sword. At first level you can potentially do 25 points of damage with that thing and if you go Beserker your able to do multiple attacks. Its kind of crazy. I've seen a 3rd level Barbarian dish out over 100 points of damage in like 3-4 rounds.
