Best air fresheners - bath and body? glade? yankee candle?

We just moved into a new house -- for the most part, it's clean, we've just painted, new carpets and aired our the rooms. I'd love to keep it smelling fresh and want to do so with plug-in wall fresheners. I know they can be hazards if you leave them plugged in when they are empty, but I will not be doing that. Would you reccomend bath and body works wallflowers? glade? yankee candle? others? I just want to put one up and downstairs to give it a fresh smell, without being perfumey or over the top.
