If you can build a UDS, then my opinion is that it beats the WSM (disclaimer: I've never cooked on a WSM, but the number of moving parts, etc. never made me want to get one). If you can't build a UDS then I guess a PBC is the next best thing.
Overall, I think the Akorn is a solid deal (another disclaimer: I've never cooked on one of these either) - you can do lo n slo cooks or blast it for nuclear cooks (like pizza). Check out JMSeltzer's videos to see what he's done on his. There have been rumors about a model with a Performer style table coming out this year.
