I have been accused by each one of you grandstanding trollops of being THE OT King. But you guys take the sodding cake and then some.
@Original Poster: You will not regret getting a Golf, any Golf. However, if I was to choose between the GTI and the GTD, I'd definitely get the former as it is a nicer car, without any doubt. Even the seats have a more attractive plaid pattern. The GTD is a very good car, but the GTI is a GREAT car. End of.
The other cars on your list are nothing but also-rans and simply have too many foibles. They are still fumbling their way towards Golf quality and status.
Always remember, you pay for what you get.
Hope you can now make the right choice.
