You might want to look in the Appliance forum. There are a lot of threads there about range hoods and make-up air. Modern-Aire and Vent-A-Hood are 2 brands that come up often.

My wife and I looked at hoods last weekend. In the area where we live, Modern-Aire is only available through approved KDs and architects, so we weren't able to look at that.

The first thing you should decide on is whether you want mesh filters, the VAH Magic lung or baffles. If you going to have a grill on your range, then you'll probably want to stay away from mesh.

The VAH Magic lung uses squirrel-cage type blowers that use centrifugal force to remove all of the grease from the air and blow it into an enclosure. The enclosure is removed once a month or so and cleaned in the dishwasher. About once a year, the squirrel cages should be removed and cleaned as well (by hand, I think). VAH also claims that their 600 CFM fan is the equivalent to 900 CFM in other brands (because you're not pulling air through filters), but some people dispute that. As neither my wife nor I are very mechanically inclined, we found the process of removing the enclosure a bit clunky, and the prospect of cleaning the squirrel cages to be particularly daunting, so we passed on the VAH.

That leaves baffle filters. The baffles have handles on them, and they simply snap out and go in the dishwasher. I've seen complaints in some forums about grease getting behind the baffles and needing to clean the inside of the hood under the baffles. The higher the air flow from the fan, the more grease that is trapped by the baffles, but it's likely that some amount of grease will always get through. Also a higher speed fan operating at a lower speed is quieter than a lower speed fan operating at capacity. So if you plan to do a lot of grilling or wok cooking, you might want to oversize the fan. You can get fans mounted inside the hood, in-line or roof-mounted. The farther away the fan is, the quieter the hood will be (although there will still be the noise of the air rushing over the baffles). With a remote fan you'll also need to oversize a bit to get the Required CFM down at the hood.

Our salesman recommended the Best brand in a baffle hood, as they manufacture the hoods sold by Wolf and many others. It seems to have a reputation as a solid mid-range hood here on GW. The Best hoods have a bit of mesh between the baffles as well. I don't know if this is good or bad.

We would have chosen the Best hood, but my wife and I couldn't agree on the hood style (she wanted a chimney style and I wanted a slanted pro-style). The only style we could agree on was a hood insert inside a cabinet enclosure. As it turns out, the cabinet company we're using, uses Modern-Aire for their hood inserts, so that's what we'll be getting. Now my wife and I just need to agree on the type of wood for the cabinets!

Finally as others have mentioned, you should look into the issue of make-up air. If you're building a tight new house with little leakage, then it probably makes sense to install it now. Also check with your town to see if it's required (many jurisdictions don't require it in residential installations). My understanding is that a simple make-up air system isn't that expensive. Putting in a heated system (if you live in a cold climate) can be very expensive though. Some people, especially those with large hot commercial-style ranges (like Bluestar), simply run the make-up air duct under the range so the air coming in goes right back out the hood. Others (like me) simply rely on the open window approach and get a bit cold in the winter. The important thing to remember is that if you have a tight house and large CFM hood, then the air is going to come into your house from somewhere. If you don't allow for make-up air in some fashion, that air will come in from an undesirable location, like your chimney or furnace exhaust, and likely bring carbon monoxide into the house as well.
