Keep in mind though that RAT would address the testing of just the Database side of the load.Load Runner on the other hand woulkd exercise the end to end flow.

Having said that though, there are other plus/minuses either side as well. Load Runner requires you to script all the scenarios and generate required data (depending on the scenario), and hence it does not fully exercise *all* the applications and components at the rate that production runs (unless and until all the scenarios are covered - a huge task in a large app). On the other hand, RAT would enable you to get a real life set of SQLs running on the database and if used well, can pretty much simulate all that is going on in the database and in fact, be able to speed up or slow down the rate of queries thrown at the database.
