Actually, yes, CA has done better.  AZ has about 792 covid deaths per million population. CA has about 422.  AZ has done about twice as poorly as CA.
In all, AZ has a pretty awful record on covid.  Most of the damage was done in June and July- but it still counts.  If you died in July, you’re still dead now.
Don’t read this as support for closing outdoor youth activities in CA.  But you need a better argument than “look how well AZ did.”.   AZ seriously screwed the pooch with their initial opening in May.
