I think both classes are pretty interesting to play.
Duelists are a lot like monks in many ways. They have several restrictions in place that makes them a bit tricky to play and limits your equipment in different ways, but they make up for it by having some pretty considerable advantages. They lose a lot of DV by not having a shield, but they're very fast and do lots and lots of damage. I like that it forces players to move out of their comfort zone--you can't just play spear and shield all the time.
Chaos knights are a tricky class. They are probably one of the most luck-dependent classes in the game, in fact. If you start with scales + acid blood + stilts + regeneration, you're pretty much a god early on. If you start with stiff muscles or wasting tissues, you're gonna be in for a really tough game. Their class powers are quite strong, and you have to balance the power gained by extra corruptions versus the risk/damage they can cause. I think/hope that TB introduces a bit more useful chaotic questing for them--they really at very least should be able to get Healing via killing Jharod--but, again, they require a very different style of play from what a lot of people are used to. And like anon says, their starting PV is just godly.
Honestly, IMHO the most disappointing new entrants are ratlings. I've found them to be very mediocre. I like detect item status, but it trains terribly for most classes, and ratlings seem to start with just terrible stats and poor starting gear, and none of their other skills are really worth mentioning. They're probably on par or maybe worse than humans in my books.
