I can remember it being Ringway! (see left for age)
I use T3 a lot, and although it's a bit of a strange maze to get through security and to some gates, I do think it's improved over the past two years.
The central bar inside has always been fine, though I do agree with al446 that the walk from the station/bus station is much more complicated (and possibly wet) than the old way of walking through T1 landside past the Donkey Stone and Burger King which are sadly missed.
