This or That: Reusable water bottles, SIGG or Klean Kanteen?

So you've finally made the decision to buy a reusable water bottle and stop filling the landfills with the disposable plastic versions, but what brand is going to get you the most in the way of "green" points? Two of the biggest brand names claiming eco-friendly status are SIGG and Klean Kanteen, and here are the basics on each:
SIGG: Made of aluminum with an inner lining made of some sort of mystery epoxy (to keep the water from contacting the aluminum). Made in Switzerland.
Klean Kanteen: Made of stainless steel, no inner lining necessary. Made in China.
Klean Kanteen seems to win this one, if only on the simple argument that since they're both made of recycled/recyclable materials, and neither is made here in the U.S. (they both have to travel a long way) the one that doesn't require the extra step of an inner coating theoretically uses less energy to produce and is therefore more environmentally friendly. Thoughts?
This argument could get a lot deeper, feel free to share in the comments!
