Why? As long as the price range of Google stays as it is I see no danger for Adobe. And as long as Google doesn't even provide an easily accessible API for raw data (or configurable multi dimension data export) I see no danger there. Did I mention classifications not costing additional dimensions/variables?

On the other hand I hope Adobe takes a very close look at API performance, segmentation et al.

Both tools have their strength and weak spots. Both might be the right tool for the right cient/company/use case. As always it depends on the circumstances.

Disclaimer: As an analyst I work with both tools. And the more I do I prefer Adobe Analytics.

PS. : The same goes for the respective tagmanager solutions.
