Mario Tennis is a worse game obviously. Mario Tennis has less content, because it's more work balancing characters and SFV has more maps. So I'd say it's in a middle ground between Mario Tennis and Splatoon. Splatoon was lacking when it came out, but at least it had a decent single player experience with bosses and some platforming levels, and 3 online modes. Not outstanding, but it's factually more content. And it was 30€ cheaper at least in Spain. Big difference.
And c'mon, the Amiibo's use in Splatoon is fair. I mean, they unlock some single player modes which consist in playing the exactly same levels with a different weapon, in what world is this suposed to be a big deal? Bashing Amiibo's use because of yes seems to be the norm today.
