Initially using display attribute seem faster, however runtime frequent changing of display attribute could be slower than visibility attribute due to engine keep calculating/rendering for the change in display attribute. For visibility attribute the engine only need to calculate/render once, any subsequent changing to this attribute doesn't make the engine to keep calculate/rendering, it only display or not display However, this is pretty much engine specific how they treat display and visibility attribute.
