I had this one on my shortlist, until I saw the triangle thingies on the back, not my cup of tea unfortunately 
Doubt it does much of anything, but I guess the aesthetic is a personal preference.
It doesn’t bother me much either way and certainly wasn’t a deciding factor, but everyone is different and there’s nothing wrong with that!
Interested to know what else is on your shortlist, as an aero bike with a real world decent stack is hard to find. I think it is the next big category as it makes so much sense for “normal” riders who don’t have the flexibility of pros.
The only other bikes that come to mind are Peters new XM Carbon frameset (Gran Tourismo) or the Dogma X….which is just ever so slightly out of budget!
