CouchDb Which is the Best Performing approach to find data using Views or N1sql : i am building an php application using couchdb (mostly), but still not completely clear on the best approach for fetching contents, there are 2 different ways to get data (if i am correct)

 1. Using View functions
 2. Querying Data with N1QL

That mean i can get same content using these 2 options..

For my developments purpose (n1sql) second option is more suitable. But still i am willing to rewrite my models to use more view function , if that approach works well (in terms good performance, less RAM and CPU usage, less maintenance costs, etc. ) 

Please share your thoughts about this

Thanks in advance
