Seiko kinetic or Citizen Eco Drive?

I'm thinking about getting a battery-less watch and I was wondering if there were any big differences between the two. I'm guessing the eco drive is a whole lot simpler, but which one works better and more reliably? And are there other watches out there with alternate power sources like these?
 
IIRC, the Eco-Drive watches are a fair bit thinner than the Kinetic watches can be made.
 
As an Eco-Drive owner, I am quite pleased with my watch. Citizen designs the watches to need no maintenance for a lifetime. (This seems to upset some of the watch snobs.) Also, several of the Eco-Drive models can store power to run for years without light. The Seiko Kinetic watches used to have a capacitor insetead of a battery, which lead to some earlier problems. Also, it seems Seiko is almost secretive about the life expectancy of their watches, as well which of their watches is actually in production and which of them are discontinued. Also, the Seiko warranty is only two years, I think. I know Citizen's warranty is five years.

In terms of long-term reliability and length of power reserve I consider the Eco-Drive to be superior to the Kinetic.

While both work well, there have been far too many reliability problems associated with the Kinetic for me to recommend one, and the power reserve is much less than that of an Eco-Drive model.

Another advantage to the Citizen design is that if you will not be wearing it for some time you can keep it charged up by leaving it in a sunny place or a table exposed to light. Kinetics can't do this.
