In short: eventual consistency is insufficient in many real-world error scenarios which are outside the CAP theorem. Go for full consistency where possible, which is more practical cases than normally assumed.
But full consistency isn't web scale! There are a lot of times where full consistency with some kind of cache in front of it has the same client quirks as eventually consistency though.

As always, the answer is "it depends".
