I much prefer DUAT to any of them.
fltplan.com willDuats!
After a few hundred flights filed its always within 5 mins of enroute times and its stupid simple without all the crazy colors (call me old fashioned). If an IFR route aint kosher it'll spit it back too, don't know if the other's do that.
I switched from Duats -> fltplan a couple years ago and never looked back.
