I'm glad you both made it out of your crash alive, but statistically the face and jaw are most likely to be impacted in a motorcycle crash and the DOT standard that half helmets are designed to pass (because they can't pass ECE or SNELL tests) can still kill you at moderate impact speeds. I wear a 6D helmet, which has game-changing slip plane technology (generations ahead of MIPS) but any kind of MIPS helmet can do more than just save your life, but prevent common traumatic brain injuries that are hard to statistically quantify but can really make a difference in actual recovery and quality of life post-crash.
