Well for me I would go for the tiptronic, purely because it's great for city driving which is mainly what I do. For me it's the best of both worlds. (in fact, my next car, a Nissan Skyline R34 GT-t will also be tiptronic).
A lot of people prefer the manual and after a while wish that they had got the manual if they went for the tiptronic, but not so for me. I think the tiptronic was the best thing ever brought out.
If you get the chance, take out both and decide for yourself because in the end it all comes down to personal preference.
