Vita had OK support at first, but Switch will get better as time goes on. The Japanese third parties are likely going to tip first, but Switch's sales in the West are very strong too, look at the recent Euro charts in UK, Spain, Germany ... Nintendo is starting to take over again grabbing top spots. In France, its just pure domination.
Switch will overtake Vita's 3rd party support, it probably actually has by far already, Nintendo just micromanages all major Switch announcements unfortunately, so we probably won't know about stuff for a bit.
