Honestly it would be hard finding three things I like about all three. So I'll just start by putting my strongest foot forward.
SONY
+ Diverse library, they basically have a very very good game in every genre out there. Something for everyone and they support games that otherwise would never have seen the light of day.
+ The maintain a very open platform. Basically allowing devs do anything devs want to do, cross platform play? go right ahead.
+ They do not bleed their IPs to death, you can pretty much guarantee that with every Sony platform, their will be a slew of new IPs, for better or for worse.
- Slow feature updates. Makes you wonder what they spend all their time doing.
- They have a habit of doing last minute marketing for their IPs, not allowing the games get as much exposure as they could.
- did I ,mention slow firmware feature additions?
MICROSOFT
+ they know how to market their games. They can make any game seem like the biggest and best thing that ever happened to gaming, and the media eats it up.
+ They made the whole concept of a networked connected console a reality.... for better or for worse.
- At their core, they do not really care about gamers or the industry. if MS had free reign over the industry, it would be a very very very sad day for gamers, everyday. They would suck us dry.
- Very poor first party support. They tend to have only one major game release per year.
NINTENDO
Drawing blanks here... Only thing I can think of that's what saying is that they make some great first party "nintendoish" games. won't list out their negatives cause well, it could just be like their positives; a very nintendoish list of negatives.
