A frequently asked question is: Which 4,000 footers have the best (or worst) views? Rather than rank them, I have used the following (admittedly arbitrary) classification:
Views from the New Hampshire Summits
Excellent 360 degrees Good Poor
Adams Bond (from north) Carter Dome Cabot
Bond (from south) Carrigain Hale East Osceola
Bondcliff Clinton North Kinsman Field
Eisenhower Flume Osceola Galehead
Jefferson Garfield Tom Middle Carter
Lafayette Isolation Whiteface Middle Tripyramid
Lincoln Jackson Wildcat A North Hancock
Madison Liberty Willey North Tripyramid
Monroe Moriah Zealand (from Zeacliff) Owl's Head
Moosilauke North Twin   Passaconaway
Washington South Kinsman   South Carter
  South Twin   South Hancock
  West Bond   Tecumseh
  Wildcat D   Waumbek

I am less familiar with the Maine and Vermont summits, having visited them only once or twice, so the following is presented with much less confidence:

Views from Maine Summits
Excellent 360 Degrees Good Poor
Abraham Old Speck Redington North Crocker
Katahdin, Baxter Peak Bigelow, Avery Peak Spaulding South Crocker
Katahdin, Hamlin Peak Bigelow, West Peak    
North Brother Sugarloaf    
Saddleback, the Horn      

Views from Vermont Summits
Excellent 360 Degrees Good Poor
Mansfield Abraham Ellen  
Camel's Hump Lincoln
