This thread immediately got off-track.
Let me talk about the OP. First of all, you discuss exclusives and third-party games as though they are separate things by necessity ("I am just poisoned against third-parties ... but I can't imagine my self playing all that many non-exclusive games."). On Microsoft platforms in particular, many of the exclusives ARE made by third-party studios. Dead Rising 3, Crimson Dragon, Titanfall, Sunset Overdrive, the upcoming Tomb Raider, etc. I know some of these are published by MS, technically making them "first-party" projects, and that some are available on PC, technically making them not Xbox exclusives, but you get the gist of it. Sony has a similar situation with Bloodborne, Deep Down, Street Fighter V, and generally a lot of Japanese or indie games.
I bring this up because if you like Bloodborne or Street Fighter V (etc), you might want to consider trying multiplatform games made by the same developers (Dark Souls, Street Fighter IV Ultra, etc). There's no reason to rule those games out simply because they're multiplatform.
To answer your question more directly, yes there are a lot of multiplatform games available on XBO and PS4 (and sometimes PC) that are not available on Nintendo platforms that are worth playing. Which games these are depend on your tastes. Your perception of third-party games seems to be jaded by their lackluster support of Nintendo platforms, and I don't blame you because they have a habit of supporting Nintendo platforms very well with bad games.
