Is there a difference between using NSURLConnection with delegate call backs and sendAsynchronousRequest:queue:completionHandler:?

Question
I'd like to understand what the difference is between using –initWithRequest:delegate:
with delegate methods and +sendAsynchronousRequest:queue:completionHandler:
.
Are there some performance differences based on the number of requests, or any other criteria?
La solution
sendAsynchronousRequest:queue:completionHandler
is an easier call to make. initWithRequest:delegate
gives you more control over things like caching, redirects, downloading large or incremental amounts of data, canceling requests, etc, etc.
