Even compared to the Wii days I think devs could put in a little more effort as far as actual new games.
Wii may not have gotten as many contemporary ports as Switch due to being more dated relative to its rivals, but it did have a fair few good third party games built from the ground up for it; the Goldeneye 007 remake, Sonic Colours, Red Steel 2, de Blob 1 & 2, Epic Mickey, Dead Space Extraction, and of course Monster Hunter Tri.
Wii benefitted from being much cheaper to develop for. Developing for the wii was closer to making a psp game then it was to making a 360/ps3 game. The control scheme also gave it reasom for exclusivity. portable mode has made developers less willing to build experiences around the joycons unfortunately.
