I actually don't think there would be a huge difference in sales between the three.
This is just some people trying their hardest to shoe horn their personal preferences down everyone else's throats.
The Galaxy games actually, given that they had a 100 million userbase to sell to and managed about 10 million and 7 million or so respectively, whereas 3D Land sold about 9.5 million on the 50 million 3DS base and 3D World is going to likely finish in the neighbourhood of 5 million on a 17-18 million ... if we're talking relative to user base, 3D World/Land games more than hold their own.
Galaxy series was obviously helped hugely by the Wii Sports/Wii Fit crazes.
