Is a change as good as a holiday for a gecko?

[Ridgeback]

G'day Folks,
After the weekly clean and hose-out, is it better to reset a gecko tank to more or less the same layout so they are on familiar territory, or are they better off with the mental stimulation of a new hunting ground. I have built a fixed background with their ledges and crevices so the sleeping quarters will be familiar. I have a range of rocks and branches which I can change in and out.
Thoughts, suggestions, opinions and mindless banter all welcome.
