The only models everyone really needs to look at is the GFDL and the GFS, thats is unless 1 of them is a outlier.The ECMWF isn't bad but just generally gives us a idea of AROUND where a system might be. Rest of the models are not too liable. Sometimes a model, like the UKmet does well, but only if it is inline with the GFDL and GFS. So in summary, GFS-GFDL rest dont even bother looking at or you will start assuming possibilities that just wont come true.
