We just came back from Azamara Pursuit from BA to Rio. We previously sailed on Celebrity, Princess, Holland, Cunard, Oceania, Costa, RCI and Carnival. This was our 12th cruise. Our benchmark is Oceania (we sailed on the Riviera last September).
Overall Pursuit is a great ship and we had an amazing time. However we liked the Riviera better. Here is why.
The service is excellent, comparable to Oceania. But sometimes things seem a bit less organized. For example, some of the excustions were delayed 15-20 minutes. Never happened on Oceania. Also there are some lines when leaving the ship and coming back. Nothing major, not even close to what you see on big ships, but still slightly longer waiting times than Oceania.
The cabin is small, the show is ridiculously small. But they are well organized, and since we don't send much time in the cabin, it was not a big deal.
