Personally, everything good I have to say about Nintendo is in past tense. Since they released the N64 the gap between me and Nintendo his gotten wider and wider.
There are key things I loved about Nintendo back in the day and almost all of it revolved around 2D platforming and/or RPGs.
Except for the NSMB stuff (which Is just about the only thing I can tolerate on Nintendo modern systems these days) it is really hard to find or enjoy any of the new Zeldas and Metroids on their consoles. The portable games are different issue.
Additionally if I want to play a bunch of RPGs I can't find but a small handful of them on Nintendo consoles. It's a sad wasteland filled with only a few bright gems, none of which are must haves forcing me to support the console itself.
