I reckon both look pretty good. I do like the Series 2 with the Neo, and unlike many, I really enjoy the tiptronic. Its pretty good too, when giving it some stick. I also enjoy changing with the lever too, nice clicking progression, although its the reverse of my XR6T.
One thing that really impresses with the Neo engine tho, is the smoothness of the thing. It just keeps revving out. Cant wait to let it breathe a bit better.
I must say that the lights on the Series 1 look better. Still, at least people notice the Stag.......I get heaps of blokes nearly breaking their necks to have a look, going WTF!
