It is indeed. My 2016 trip, it allowed me to get in 25 dives, to dive by all 3 Cayman islands (mostly Little Cayman), very simple logistics & easy advance cost determination, and by willingness to room with a same gender roommate, no single supplement (unlike some land-based accommodations), plus no need to rent a car. I didn't face the extra cost of 'eating out' (said to be pricy) or the hassle of preparing my own meals. Booking during a big Aggressor sale knocked the price way down.
I'm not saying the live-aboard option 'beats' the land-based; different people have different needs. But it is a good choice for some of us.

I think that there may be some negative feelings about the Aggressor among some of the Cayman dive ops. I am not pointing fingers at any specific dive op but one time we did encounter some hostility in Little Cayman. Perhaps it's because they compete for the sites that are available to the land-based dive ops, but I am sure that the Aggressor also has to pay the fees required by the harbor, the government, and CITA.
A few years ago, we were staying on Little Cayman and the 2 divemasters on our boat made several, small, spiteful comments about the Aggressor, like never referring to it by name and calling it that "Big ugly boat over there!"
Finally, a diver on our boat asked about the comments, and one of the divemaster went into a tirade against the Cayman Aggressor.
He said that they "always grab the best sites" and that they "sit on one site all day and never move the boat", and that they "don't care about the environment" and that they "chum for sharks!"
I thought that his comments were surprising and rather unprofessional, but I am sure that the Aggressor does grab the best sites first because they don't have to go back to the resort, but they always moved the boat at least twice per day - to grab another great site - and that was fine with me when I was on the boat! But they always seemed respectful of the environment on our trip, and they did NOT chum for sharks.
Anyway, there may be some antagonism between the Aggressor and some of the local dive ops, at least on Little Cayman. We didn't encounter any negative comments about the Aggressor during our most recent trip to LC, but there was bad weather the first couple of days and the Aggressor didn't make the crossing, but I still feel that the Aggressor represents another option to consider for divers that want to come to Cayman and do a lot of diving.
