The 'cost to change' figure sounds pretty good.
Depends what your plans are for the car and how you currently drive yours. If you're looking to remap then it's go to be a good idea.
The standard GTI 'feels' quicker / more responsive under normal to modederate driving conditions - could be argued 'deceptively quicker'. Obviously, it's not quicker, as we all know.
Most motoring journo's prefered the feel of the standard GTI for this reason IIRC, despite the Ed30 being the slightly stronger performer.
As said, depends on your plans for the Ed30 and driving style.
