Anyone know which arena statistics site is (more) accurate?

So for a long time i've referenced http://www.crossladder.com/arena/stats/ for info on which classes/comps were doing well at the moment but had seen people referencing http://www.arenastats.com/index.php?...600&mt=5&mg=20 a lot more recently, and if you look at the 2 sites you clearly see one must be very wrong because the data is WAAAY different. starting to think arenastats.com is the accurate one but then wondering how crossladder.com pulls it's data and what exactly they're doing to be that wrong? anyone know any more about this?

you also have www.worldofwargraphs.com which seems, imo more accurate
