Cloth Diaper Users

Je
I am a FTM and my husband and I decided to give cloth diapers a try. I did some research and found that there are one size diapers, sizes diapers, pocket diapers, all in one diapers, etc. It's a little overwhelming. I think I want pocket diapers so if our baby is a heavy wetter I can put in an extra insert. I have also mainly seen Fuzzibunz and BumGenious which seem like pretty nice diapers. My question is, have the one size diapers worked for your kids or did you need the different sizes and how many of each size did you get? Are there any other brands you prefer? What are pros and cons of the different brands. I prefer getting info from people who have first hand experience instead of just the Internet, but unfortunately, my husband and I will be the first to use cloth out of our family and friends so any help is much appreciated. 
Edit: one last thing. Do the brand of inserts you buy need to be the same brand as the diaper?
