Fantastic Fan vs. Maxxair

I've put MaxxAir Deluxe units in my last two rigs, both of which already had FanTastic fans so that I've had one of each in both rigs at the same time. I've found the MaxxAir less prone to bearing chirping/squeal over time. Hard to say which moves the most air as they both get a pretty good breeze going when on high speed. My MaxxAir units generally need the screen pulled down and cleaned more often than the Fantastic fan, which may or may not mean anything. The Fantastic fan has the rain sensor, no hood so it is generally closed when not in use. The MaxxAir has a built in cover and it is generally left open whether the fan is in use or not.

My own thoughts are that either unit does a good job.
