Bosch PS31 vs Milwaukee M12 2410-20 3/8 in 10mm cordless drill test

I recently got a hold of new and improved Bosch subcompact 3/8″ drill model PS31. Unlike PS30, it comes with new BAT412 batteries which are based on Samsung SDI 13Q cells (same cells as Milwaukee uses in their M12 line), smaller body and more torque.  The following picture is PS31 (left) with PS30 comparison.
