Switch has been out a lot longer and has a bigger company behind it. I don't think anyone ever expected SD to catch up in sales. However, the SD has clearly had an impact on the handheld market. And without tinkering, it functions way more like a console than a full PC.
And I don't know what setup you used for switch emulation, but I've emulated several switch games with perfect success. I certainly mostly play my switch games on switch, but I've put a handful on the deck for travel and it's been great. Along with my 3ds games since my actual 3ds went to electronics heaven.
