If you read Consumers reports rating of HVAC and Furnace Brands, be sure to read the footnotes/fine print, the margin is quite small between brands. Plus it is not based on any testing, just a survey of consumers.
HVAC eqipment is not plug and play, like a TV or refrigerator. The final manufacturing is in your home, by the contractor connecting all the variable pieces, if they do a poor job, the Brand you choose will do a poor job!!
Check the Department of Energy's website, poor installation can cause a 30% efficiency loss!
The brands you mention are all decent furnaces, but choose the best Contractor. That said, I prefer Carrier.
