I have two and they are both very good smokers. The sump area needs to be kept very clean or they get pretty foul. It's one extra step in the cleaning process, but it's not that big of a deal to me.
As far as them being "better", I don't think so. They're just different and they perform the job they are designed for quite well. I use mine for aromatics as those tobaccos seem to be the wettest smoking.
