water in the back country

Has anyone used the platypus gravityworks 4.0 ? I was looking at getting one of these any pros cons versus the other brands?

Thanks for all the information and opinions on this thread for water filtration. I have and use a Katadyn Hiker Pro and have not had any issues with it and thought it was very easy to pump. I also carry iodine tables for back up. I never realized how many options are available for filtration.
