Hello,

I have used both, DataSet and DataReaders.

About DataSet they are quite easy to use but not a good approach if your
site has to support a lot of traffic, or if you have a cheap hosting (well
here things depends more on things like the cache that you are going to
apply)

About DataReader and custom business objects, you need to make more
boilerplate code, use custom datasources and custom paging. It's quite
optimal because you just take from the SQL Query jsut the records that you
need for paging, but you have to implement all the queries and code to
perform sorting and paging. Take a look at this links:

If you need more help just give me a shout.
