Independents

Is the One considered an advanced design over the Three?

 

I know they introduced the 3 at Basel 2013, then the 1 this year, and I understand that the 3 is oil-filled, but the 1 isn't.  The only functional difference I think I see is that the 3 has a date fxn while the 1 does not.  Is the more recently introduced 1 an advanced design over that of the 3?
