Similac vs Earths Best Organic

Background my daughter was born full term 40 +3 at 5lb 13oz. Me and Dad are small people and we’re bound to have a small baby. At her 2mo appt she was in the 2nd percentile for weight and now at her 4mo appt she’s dropped to the 1.2 percentile. (Despite gaining weight every week. They think her weight gain is not enough weight gain.) The pediatrician wants me to begin supplementing with formula. We EBF mostly because she rejected bottles so this should be fun. Long story short this pediatrician is very rude and pushy. She likes to make underhanded remarks that I don’t appreciate. So I’m hesitant trust her judgement in general. She was very stern and said I needed to give my daughter Similac. They gave me a small can of Similac Neosure for Preemies) I’m not against trying supplementing but there was no conversation about what brands of formula I could try etc. I’m not necessarily against Similac but I would rather a more organic option. I purchased a can of Earths Best Organic but haven’t decided on which to use. Or if I’d even prefer a different organic brand.

Anyways- I don’t know much about formula but I’m considering trying Earths Best Organic. For the those of you who formula feed what do you suggest? Any advice ?
