Nintendo: Personally I dont think the Wii is very good. Its way too overrated. The best part about it is probably the cheesey but slightly entertaining Wii Sports.
Microsoft: I love the 360. To me its the best console out there right now! It has a few good sports games but mainly shooters which is great.
Summary: Clearly I pick Microsoft and the 360 because I think that they have better graphics and has way better games.
Nintendo has the Wii which almost only has games for little kids. Its lame and again way overrated!
Umm this is a weird topic. Microsoft does have the better console. (Xbox 360) I personaly have a live account. The live community is really what sells it for me.
The Wii is a very revolutionary idea. Its someing that has been tryed and failed terrably. Wii has succeeded in being the most different console.
The Ps3 could be the next big console. I know im going to get some back feedback on this but... the Ps3 has the free internet play and is faster then the xbox. The only holding Ps3 down is the lack of great games. If Ps3 has a good video game selection like the 360, their would be no contest over the better console. All Ps3 needs is a GoW or a Halo for it to be a good console pick.
Microsoft. Microsoft has many great achievment including the Xbox and the new Xbox 360. They have also made great stride in thier game's graphic and gameplay. Of course Nintendo has been around longer and has made a lot of progress through the ages, but I choose Microsoft.
