Is Midir even worth it?

Is Midir even really worth it? Are the weapons you get from him worth this stress? I’m already trying the mist cheese and it does a lot of damage if it lands but most of the time he flys off as soon as I get the spell going and he manages to get me with the lock on disengaging on its own and throwing me all the way off or he corners or he one shots me if I dodge a second late with his second phase laser move. Gael was an amazing fight but I hate this fucking lizard
