That should be a really huge OR
It's qgis.org OR ubuntugis
If you do both you end up with potential conflicts.

The version of QGIS is actually the same, -# is actuall just an
increment that gets raised every time someone reuploads the same package
with a minor packagin fix.

What differs is the versions of underlying libraries: gdal, geos, and proj

For many people having a newer gdal (1.10.x) and a newer goes fix a good
deal of bugs in support certain format reading/writing and certain
spatial analysis operations.
