Firstly, I think fins are a really personal thing - depends on the person and what works for one may not be good for another. If you can it is good to try them in the water before buying.
Have used blades (tried them for about work dives when they first came out) and quattros. For me there is no comparison - quattros are much much better - lighter more efficient, more comfortable and faster. Buckles are nice to if you like plastic buckles. But that is just me. I also really dislike jet fins.
