I don't disagree with what you wrote above. The company hangs its hat on its support but I yet to be impressed with what I've received.
I wouldn't base your decision on whether or not to go with the surface based off of the installers perspective. As a consumer, you need to look at the end result and long-term benefits vs the cost. I too have losses that will take years to recoup - if ever.
The ideal pool for this coating is a remodel where the plaster is in good shape. The trouble with this is that most people wait until their pool is crumbling and falling apart until they decide to do anything about it. Now the plaster needs to be chipped and replaced prior to receiving the coating all at an expense well above just about anything else... That's a pretty hard sell.
For a new construction pool, the interior finish is usually the absolute last portion of the build, often when money begins to get thin from all the previous upgrades that were added along the way. I've had 4 new construction pools that were going to go with AB that all fell through due to lack of funds at the end of the build.
As the consumer if you want a durable, smooth, uniform and long lasting finish, then this is it. You just need to determine if the expense is going to be worth it in the long run.
Now if you were looking into becoming an installer, I would pay very close attention to what the other installers have said...
