I'd say go with Nintendo.
If your only goal is to get your game on consoles, they are the best. Sony is great too, but it takes more work/dedication on your part. My game is exclusive to PS4 so obviously I think it's worth it, but I've been working on it full time for over a year. You don't seem like you have that amount of time to spend.
I have no first hand experience with Microsoft, but for new/smaller guys they are the worse of the three.
