Perle as an all around bittering hop is definitely the most versatile. It has a higher AA%, so you need to use fewer to achieve more bittering. You saying that you do mostly lighter beers, this would get my vote.
Tettnang is low AA%, thus you would need to use more for the same amount of bittering.
Columbus is a very resinous, dank hop. It is best in American style beers (Pale Ale, IPA, American Stout). While it has a high AA%, it is both a flavor and aroma hop, well-suited to any part of the boil. It has quite a distinct aroma, IMO.
