Downdraft, from all I have heard and seen, are the pits - unless it is so overpowered that it sounds like a jet engine taking off when it is running, there just is not enough airflow to overcome the convective rising of the heated air over the cooking area. They also draw off the back of the stove typically (though some do downdraft through the burners) but that airflow is not consistent across the depth of the range, and also steals heat from the range and pots and pans.

Recirculated ones can be used - I have never liked them because they really do not remove most of the aerosolized grease (as evidenced by the normal heavy grease buildup around that type unit and on the ceiling above it) so a lot of the grease gets recirculated in the kitchen air - and they do nothing about odors unless they have charcoal filters, which have to be changed frequently. And of course, frequent filter cleaning is necessary, which means a lot of manual labor - or risking greasing up the inside of your dishwasher if you use that to clean them.

My recommendation - conventional ducted overhead metal mesh filter and fan installation, probably at least 600 cfm and preferably multi-speed with max 1200 cfm capacity, with the ducting probably running the shortest way possible through the overhead floor joists to an outside wall vent. Of course, the lower over the stove the hood is placed the better the collection of moisture, grease, and odors.

Ducting should definitely be installed with duct joint sealer on the joints because of the risk of some grease buildup which could drip through joints, and the outlet damper or hood should be easily removeable to allow for swabbing out the duct every few years from the outside if it builds up grease in the duct.

Heating and A/C is the Search the List category for a contractor to install this.
