everybody has a different play-style so there's bound to be people that have different opinions but i don't see a world where dry baby is in the same tier or lower than bbf, dry baby costs 25 less, has the same explosion effect and damage, counts as a defensive baby so not only it's a better 3x3 explosive but it also synergizes with frosty mint, sanuine bond + isaac's fork; bbf has no synergies or upsides in comparison
Simply because I don't use it over cube of meat or Tooth & Nail because of the synergies being the focus. Sharp plug, Frosty Mint & Sanguine Bond are all broken as fuck. I don't even use BFF neither, I usually am fine without stuff like BFF or Snowball. But I agree I can't say any of the babies I don't use are bad, none of them are, they're just not for me.
