Making myself crazy over deciding a formula

My baby is 6 weeks old and we are going to start combo feeding while using up the rest of my freezer stash. My husband and I have done so much research it feels like we’re going in circles. Any insight on whether kendamil organic or Bobbie organic is better? Or nonfat milk formulas?? Our girl has reflux and spits up/coughs more than the average baby for sure.
