One more vote for the MSR. If you're in a situation where water is critical (e.g. the desert, no water and lots of thorns) bombproof trumps light. But if water is plentiful the Platy is a lighter choice too.

My only concern with the MSR is all the connections: A threaded cap, a threaded hole in the threaded cap, a flange to hole interface, and a press fit for the tubing. Just make sure everything is tight. The good thing about this system is versatility. You can choose between a spigot, flip top or drinking tube. And MSR sells replacement parts for all.

There is a good DromLite review here.
