Advantages of USS vs OSS?

[BookFinder]

I've got my interests narrowed down to three ... or maybe four SWB bent models.

Several of them are available in an under seat or over seat steering option.

So, from those of you who already own a bent, which steering do you prefer, and why?

And, what are the advantages/disadvantages of each steering configuration?

OSS: more aerodynamic, somewhere to mount your computer, easier to manouever the bike in a confined space, works with twist shifters
USS: relaxed, linkage(?), best with bar-end shifters
