I dive the same places pretty frequently, and do awesome new countries a couple times of year on vacation. I enjoy diving local, especially running into and interacting with the same friendly sheephead multiple weekends in a row. My dives are to have fun, not to intentionally "get better". So I would rather keep diving the good places I know that have lots of fish (and other good places along the coast) than make a trip specifically to do some boring lake dive with no visibility.
But we all do this hobby for fun, so I guess if it's fun you to build skills than enjoy the scenery, more power to you.
