OWL Reification vs. RDF reification

Hello,

I've asked a question on Stackoverflow about the difference between OWL 
reification and RDF reification, but got no answer nor comment:

https://stackoverflow.com/questions/45610092/owl-reification-vs-rdf-reification

In short: in the context of a dataset using owl properties, what is the 
difference between

_:b0 a             rdf:Statement ;
      rdf:subject   bdr:T123 ;
      rdf:predicate rdfs:seeAlso ;
      rdf:object    bdr:T1129 ;
      rdfs:label    "reification 1" .

and

_:b2 a                     owl:Axiom ;
      owl:annotatedSource   bdr:T123 ;
      owl:annotatedProperty rdfs:seeAlso ;
      owl:annotatedTarget   bdr:T1129 ;
      rdfs:label            "reification 3" .

and how can I know if I should use one or the other?

Thank you,
