There are pro-s and con-s of the 3store backend

+ 3store provides RDFS inferencing built in
+ 3store provides RDQL built in
- The 3store backend to redland hasn't been tested much.
- 3store doesn't provide all the redland RDF triples-based API
- redland doesn't pass on RDQL queries direct to 3store but uses it's own

The MySQL backend has it's own feature set.

Some of this is covered in http://librdf.org/docs/storage.html
