Same here, I prefer Eheim. I really like the simplicity of the Classic, but the ECCO is fine for slower flow needs and the Pro series is good if you like all the gadgets.
I wanted an Eheim. I liked the quality and the model with the built in heater. I liked the idea if one less bulky item in the tank. Since the one I wanted was almost $400 with media and the fluval 404 was on sale for $97 I bought the Fluval.
XP's are a lot better. All I hear about fluvals is that the small plastic pieces break and the filter lasts about 7 years. Eheims last 15-20 years according to some people. Petsmart's website has eheim 2213's for $65.00.
