Non-redundant protein sequences database versus UniPROT/SwissPROT database BLAST results

Question

[tony]

When I take an amino acid sequence and run blastp through the non redundant protein sequences database and do the same with the UniPROT/SwissPROT database what is the difference in output results.

Aren't both databases curated. Under which scenarios would i used either database for my blastp?

Thanks
