From an enthusiast point of view, I like to have iconic models if possible. G-Shock is Casio's iconic line, it's rightfully legendary.
From a practical point of view, G-Shocks are the best watches in the world IMO. Super tough, packed with features, and a style for everybody. I wear a G 90+% of the time, they are just the best.
To be honest, all Casios will be good high quality watches. The one you picked looks really good to me. But as an enthusiast, I would definitely try and find a G which looks similar, because it will be even better.
