I have 2 fermenators. I have had great experiences with them.
The triclamp fittings are better, but as gsandel said, changing your fittings can be a hassle.
I've never had an issue that I could attribute to the fittings - I soak with hot PBW, sanitize with iodophor or star san after every batch and once or twice a year, I break it entirely down and do an extended soak on all parts, and an acid soak to get the beer stone off.
I'm sure the Stout one is just as good, they just weren't around when I got my first blichmann.
