First gen (I think) of Giro helmets with MIPS were less comfortable than the non-MIPS models (I had a Synthe and Foray), but I have two Aegiles helmets now that are far more comfortable, and that's at the low-mid range price point. Earlier in the year I had a crash on a solo ride wearing a MIPS helmet that resulted in a minor concussion I wasn't totally aware of until I got home. I would not ride without one now because the brain is mostly non-repairable.
