Now im more in conflict. Should I cancel the snap or suck it up and drive “slow & low” for 6months
Hard to say - it is unlikely that you'll save money and you give them lots of data that they can use (against you) for future rate adjustments.
On the positive side, the beeping will make you a smoother driver - if for no other reason but to shut up the beeping.
You really need to ask yourself what your priorities are because these two devices are on opposite ends of the spectrum.
Yes, you can use the AP to log data, but that's not why you are getting it - you are getting it to tune your car so you can go faster quicker - while the snapshot is to really to get you to slow down and turn your GTI into a Yugo.
