Well this question is very easy to answer, but also quite difficult. Subjective with perhaps a dose of bias.
For myself, I have always been an admirer of Nintendos products. Theres just this mystical charm that exudes from Nintendos IP's. Most of the 1st party games seems to be accessible, and most importantly fun. They cover most of the so-called mainstream genres and have created some new genres as well.
Microsoft has come along quite nicely. Although I'm not a FPS fan(get headaches playing too much), they have covered other genres well and have a healthy following. It's not fair to call the Xbox brand a FPS console as all the consoles have a healthy variety of genres, and Microsoft has expanded its genres as well.
Now onto Sony, I think they have steadily gotten better, especially with finally carrying on with some older IP's and creating some excellent franchises. I think they are a very solid second with M/S close by. New IP's are great, but having a continuation of IP's with quality sequels is what creates brand recognition.
But when comparing to Nintendos time honored franchise IP's, its difficult to measure the nostalgic value and charm that goes along when playing a Nintendo Published game.
Still, all 3 cant even begin to compare to my favourite publisher, Blizzard, as this company has put out my favourite games from my most favourite genres that I still cherish today.
Just my 2 cents.
I game. You game. We game.
I'm a videogamer, not a fanboy, but have a special place for Nintendo.
