The winner is determined by who is happiest with their filter and how their fish are doing.
I would like to add that I have since acquired a Fluval FX5 and it is filtering a 125G tank, along with an Eheim 2260. I've had no major issues with the FX5 operation but will admit that I find it a pain in the butt to clean versus the Eheim 2260. It really does take me twice as long to clean as the 2260 probably due to the plant material that gets trapped in the FX5 sponges.
I also don't care for the bottom mounted pump as ingested sand tends to plug it up despite locating the intake strainer 6" above the substrate (dang cichlids!). I don't use sponge pre-filters due to their frequent cleaning requirements.
