Any of the aquariums I have seen that have an external pump are much quieter than the Mag 12 submersible pump that I am currently using. The next sump that I build will definitely be built for an external pump. Other advantages of an external pump is that they are normally more energy efficient than a submersible pump and they run cooler.
If you are going to use a Reeflo Snapper as a return pump just be aware that you will be putting a lot of flow through your sump and could have micro bubble issues. I would definitely consider putting ball valves on the discharge side of this pump so you could "throttle back" the flow if necessary. I think these pumps put out around 2500 gph before friction loss which is a lot of flow to be putting through your sump.
