Range hood vs. over-the-range microwave - which vent is better?

I need to replace my range hood which is vented outside. I am considering buying an over-the-range microwave which can also be vented out.
Range hood has a two-stage 200 CFM fan
Microwave (I am looking at GE Profile XL1800) has three stage + booster 300 CFM fan. However, microwave duct has several elbows which decreases vent efficiency, and range hood pretty much blows straight out.
I have heard an opinion that over-the-range microwaves are not as good in terms of venting comparing to the range hoods.
Any opinions on that?
Thanks,
-Stan

the only experience I've had with the over-the-oven microwaves is with my parents. they've had some problems with their farily expensive GE unit that is only a few years old. The motor for the carasel has gone out, the controls don't always work correctly, and the plastic door handle and 'grill' have both broken.
I blame some of this on the extra heat the unit has to endure when the cook top is used. When I remodel my kitchen, I'm staying with seperate units.

I've had an OTR microwave for about 20 years now. The venting is mediocre, but the added convenience of having a second oven (new one is a micro/convection) outweighs just a plain hood. Your preferences may differ.

Is your microwave recirculating or vented outside?

Yes. It goes up through the cabinet above into the attic space, then over and outside.

I ran my vent from my OTR microwave into my attic. Should have extended it thru the roof but will do that this summer. I added thermocouple sensors that turn the fan on (low) automatically with an adjustable thermostat set for 90 degrees that I picked up at the autoparts store. I really like the setup.

Very cool. How did you run the wires out of the microwave?
