Overwhelmed with baby registry! Diaper brands, bottle types, etc

Cyndi • I am married to a truly amazing man who I am proud to call my husband and best friend. We are expecting our 1st baby!
First-time mom here and feeling totally lost and overwhelmed with registering. How do you know what the best brand of diapers and wipes are? regular bottles or those ones with the drop in plastic bags? Why are there so many different shapes of pacifiers?? Do I REALLY need a diaper genie? And don't even get me started on the number of different strollers to pick from!!  Any advice would be greatly appreciated, ladies.
