Are you conspicuous or inconspicuous? Do you like to stand out or let yourself fade into the background? There's no right or wrong answer. Sometimes either action is required.
But I would make one recommendation. Ask yourself what your motivation is. What is driving the decision? The particular situation? Or the ego?
And if the latter, consider trying the alternative approach.
My observation is the ego can get you into some trouble. It might just get you caught. Camouflage is an excellent evolutionary development. Give it a try, especially whenever you see the ego looking for some extra attention.
