TL;DW: Small sample size aside, it looks like the brick layers could be marginally stronger in some ways, but it can be weaker if you don’t also increase the extrusion multiplier since offsetting a column of circles down by half a row in a grid of touching circles will make the circles not touch (hopefully that’s an intuitive explanation of the need to increase the extrusion multiplier).
