Mount Tom on the Holyoke/Easthampton line in Mass is short of stature but splendid of view. Topping out at 1202', with almost 1000' of prominence, it yields long views across MA into CT and VT and nice views of Monadnock from certain spots, plus views along its extraordinary two-mile-long cliff wall and down from its top. Heublein Tower atop Talcott Mountain in Connecticut - only 954' at its summit but Hartford County's most prominent peak is an easy, short hike that when open, between Memorial Day and early November, affords a commanding 360 degree view from its obs deck 125' above ground level, the best outlook in Connecticut, imo. The hikes up to it, especially from the north, are beautiful, to boot, with a mile-long cliff wall of its own like its cousin to the north. Both these Metacomet Ridge peaks could be included among the runners-up. West Peak in Meriden and Mount Higby in Middlefield/Middletown are gorgeous, too, and relatively easy.
As for Bear Mountain, CT, I love it, but it could be removed in favor of Mount Race/Race Brook Falls next door - both aren't needed, Race takes in the Catskills as does Bear, Race's cliffs afford a more dramatic view and hike, and Race can see Greylock, where Bear cannot. That being said, the view of Race, Everett and the Twin Lakes from Bear's rockpile is dramatic and beautiful. I've hiked it eight or nine times, so I may be under-rating it simply due to being accustomed to it.
Note to those yet to hike Bear: be sure to visit the true summit, as well, about 150 feet WNW of the rock pile - it offers better views to Frissell, Ashley, Gridley, the Braces and the Catskills to the NW, plus you can properly bag the peak, a few feet higher than the grounds near the big cairn.
PS: As re Mt. Eisenhower, I agree it offers gorgeous views, especially from its flanks. I can compare it only to a limited data set, as well, but I can only say it was gorgeous - hiked it on the summer solstice this year, a beautiful day, and got extraordinary views of the Presidentials. Definitely a favorite.
