You are bumping up last gen's number by calling TP an entirely original game, it was actually a port of the Gamecube game (even though the GC version shipped a couple of weeks later) Development and initial trailers for the game were completely on the Gamecube and was scheduledfor release in 2005.
So in fact we got 1 polarising but original HC Zelda, 2 moderately acclaimed HH Zeldas and a port of the Gamecube's Twilight Princess.
Whether this gen is better rests largely on the quality of Zelda WiiU but I would say it's already pretty close given ALBW and the high quality of the remakes.
