I agree on the Duskblade bit, as its required style is rather different from my preferred style, and I admit that I don't quite 'get' it. The Scout, initially was much the same for me. Its constant need for movement meant that it only got in one attack with its extra damage (which was notably less than Sneak Attack). It was also exposed to more potential AoO due to its movement, but its increase to AC from movement, combined with a few of its other specials (including Tumble as a class skill) made it workable.
It took a while, but it has managed to grow on me, so I actually hope it wins this tournament (along with the Warlock, another class that grew on me once I realized that a few changes to a few of its abilities and incantations would allow for ones of any heritage - fae, celestial, etc - and thus any alignment).
