Kendamil vs Good Start Plus vs Enfamil ?? [Ab] @ 9 mos

Going to be starting my LO on formula soon, have been exclusively pumping and he is 9 months now. I am considering the above brands for formula...

Any input about experiences or insight about pros/cons of these brands ? Especially starting an older baby who is eating solids- for example, would something like enfamil A+ be overkill? I get so overwhelmed with all the options
