Corner overflow or just a hole?

[PFisher]

At the end of this month I am moving into a house and am planning a tank upgrade. As part of this upgrade I have am purchasing a new tank and have the chioce of a corner overflow or a hole with a PVC elbow as my overflow. The corner overflow is much more costly, but is it worth it.

I am looking for opinions as to what will look better and be more functional. Thanks.
