I don't know what others think but my opinion is Ubisoft lineup for Wii U was much better and more diverse than current Switch support. Two Assassin's Creed games, Watch Dogs, ZombiU (imo, it was a much better exclusive than Mario Rabbids), Splinter Cell Blacklist... All same date ports and they ran excellent.
Switch's general library lacks diversity, some modern genres like FPS, TPS, open world action and arcade racing are under represented. Ubisoft can fill those spots with their franchises perfectly and they don't have to be modern ports from PS4 or Xbox One. Even last gen ports would be appreciated. Like Far Cry, I don't understand why Far cry 3 Classic skipped Switch.
I do agree their volume is a bit low (for now) but to be fair Watch Dogs was notoriously not a same day port on Wii U.
But in general it will probably be more worthwhile to compare support these platforms received at the end of their lives, not just 2 years into the current one's.
