I have a 900 cfm Viking hood with internal blower. It's ok but not exceptional performance wise. Quiet it is not but hoods make noise.

What is exceptional is the excellent halogen lighting and ease of cleaning. The baffle filters are very heavy duty with multi mesh. They go into the Miele dw and come out perfectly clean.

I have an electric smoothie, not gas, however so I don't have discoloration that a friend with a ag Wolf gets, f.ex.

Some of it depends on the range being installed. With a high power gas range I don't think I'd be happy with this hood. But it fits my application. And it also depends on how much cooking and the type being done.

We are very happy with our ModernAire Hood. We have a 48" wide 27" deep 1200 CFM PS15-30. We went with ModernAire mostly for the styling. We wanted something with a little color and curves. They were great to work with and let us tweek the dimentions a little to fit better (I think ours is 28" high). We've been using it for about 6 months now and are happy. It is not exactly whisper quiet, especially on high, but you can carry on normal conversations. I usually put it on low if I'm cooking anything that generates any smoke at all. Only used high (or something above low on the dial) a few times when grilling or burning something in the wok. It is pretty easy to take the baffles out and put them in the dishwasher for cleaning. I don't know anything about the Viking. Our old kitchen had a Broan with worn out bushings that you could hear a mile away.

Sorry about the photo being a little out of focus. I really should take some better pictures. We also have not yet finished our backsplash tile.
