Dude, don't be lazy, there is a ton of shit out there, just move the mouse hand and click. Do some research and get a little informed instead of just listening to a bunch of douchebags on the internet.
Having said this, I'll put my douchebag 2 cents in as I've done alot of reading on this, so this is just my interpretation of what I've read. I know that there are some engineers here, so their tuppence worth will be insightful. In summary, it seems that FSR and DW seem to be the best design, although the evolution of stable-platform suspension has tightened the playing field. You can curse Specialized for patenting the Horst Link, and also thank them for forcing everyone else to be more creative. The reality is that everyone has come up with creative stuff to get around the Horst Link patent or not pay royalties to Specialized.
Single pivot is the least complicated design, but probably the most reliable. Downside is it brake jacks on decents. My next bike will be another FSR or a DW bike. My friends with VPP like their bikes, I've ridden them and frankly after 5" of travel, you really need to put time on the bike to feel the difference between one design and another.
