There aren't enough details about either at this point to use the bolded points as a deciding factor. Sony may be moving to an online fee model similar to xbox live gold with their PSplus.
I'm not sure what compatibility issues you're speaking of. Aside from the GPU and system RAM (which based on how MS set up the embedded RAM may also be a wash as far as performance despite Sony using GDDR 5 instead of DDR 3), the actual consoles hardware are identical.
I would say at this point (pre-E3), by far the biggest issue is the lack of info about games for the Xbox.
