I am designing a drop down panel which houses a collection of quick links / bookmarks to other areas of an intranet. Users access the intranet through a laptop or desktop pc running windows or mac osx, as far as I know no one is likely to access via a touchscreen device.
I am currently trying to choose between two options of how to layout the links in the drop down:
The tiled view is inspired by the new windows metro ui, and I think would end up looking aesthetically nicer. But which do you think wins in terms of usability?
Or perhaps, what are the usability pros and cons of each?
