My bro has a button clutch in his rally Esky, but I'm not enlightened as to whether it's brass or not.
Big advantage of a button clutch - the friction plate doesn't have to work as hard and heat up by slipping all the time. Also helps out the gear box a bit cause you are less likely to get lazy with the clutch.
Big disadvantage - if you try to down change into a corner, without decent heel-toeing or some double clutching, you will get compression lock up like all hell. Also a pain in the arse to launch on the street 
Although they say it's a button clutch, they do have a bit of slip, but there is about 3 or 5mm or so of movement from going from all-grip to zip.
Also, mechanically, you have to realise that when you upgrade your clutch, it's less likely to break (duh). But think about it, if you make the clutch less likely to break, then the other parts in your drivetrain have one less bit of give in the system. A few too many hard or rough launches, or some bungled gear changes and you could see your gearbox go, or your diff or something like that. Systems like drivetrains are designed with a few weaknesses in mind, so that the most expnsive or hardest to replace thing doesn't break.
As far as I am aware, a heavy duty clutch is simply a more expensive clutch, that lasts longer (maybe made of more heat resistant material or something heavier), but may also reduce the amount of slip you are able to get. Not to the point of a button clutch, which is essentially a *bloody* heavy duty clutch. I think that a heavy duty clutch might also have more clamping force (maybe an uprated cylinder) to allow for more horse power to be fed through it.
Don't take my word for gospel though.
