If you can, I would order both, give both pairs a test drive, listening to music you know very well, and keep the pair you like better. Every monitor is different, regardless how accurate they are. So in the end it comes down to a matter of personal preference.
You won't go wrong with either pair.
Consider adding a sub as soon as you can, as you will need to hear what's going on in the sub bass range with techno and techhouse.
