Which would yo choose: XBOX Live or PSN?

if you were only allowed one online gameing service which would you choose between XBOX Live and PSN as they stand now? and y?

would you choose different if they were both free?

and would you choose different of they were both pay services?

I would choose Xbox Live. In fact, I'm rarely on PSN as it is, but always on Xbox Live. The scenarios you described wouldn't change that.

I put a premium on how each fosters a sense of community. Xbox Live just does that better in terms of dashboard layout, feature set and services that support the community.
