The short answer is "both": /guid/9202a8c04000641f8000000000036eca  
and /en/space are two names for the same thing, so those two URIs  
denote the same non-information resource. One happens to be more  
readable than the other, of course.

Adding sameAs links for this kind of thing is on the to-do list, but  
you could safely do it yourself.

(There is a slightly longer answer: to the best of my knowledge, GUIDs  
are immutable, whereas MQL identifiers are somewhat time-dependent, so  
for reliability's sake the GUID is a better choice. If I'm right,  
that's just an impedance mismatch between Freebase and the RDF world,  
and it is unlikely to bite anyone in practice.)
