The 2 car choice mentioned will be at 2 different price points, unless you are actually considering a Golf R ??
If that and transmission choice of a manual is no issue, IMO wait and get the AJ OPC - this vehicle sounds like it will set a new 'FWD' hot hatch standard and should come close if not match up to the Focus RS but in a much nicer and modern looking package and be much better equipped...should also cost alot less than the initial ask for the Focus RS.
Another serious choice (as others have pointed out) is the Megane RS250, they've just released a new limited edition - the Monaco RS250 which adds more kit to the existing model which makes it more like a Golf or the upcoming OPC in terms of interior trim levels, pricing is similar to the Golfs...
