What Bone has is a signature style of flow that people to this day have been influenced by, including Migos. Their catalog has some wack stuff scattered around, like any other group, but after comprising a 30+ playlist of my favorite Bone tracks, I'd say they have every reason to argue their position of the best ever. And I'd also like to add that E99 Eternal alone is one of the greatest rap albums ever made btw.
And I highly doubt Bone is broke. Y'all should learn how royalties work and also consider that they are still a touring group, getting paid of streams, other ventures. But I agree that this isn't about money, it's about who can make the best music. From what I've heard of Migos, they the young niggas that rap like a bunch of Tazmanian Devils, right? You can find a clip of Bizzy in the studio now, with real words, that shits on their woladfaaad aldio woaaera. That old ass verse he rapped in his first response to Migos talking shit is a show stopper, along with the elder showing them young cats love.
What I will say about Bone is they have strayed into pop-ish sounds as of late. I'll debate their old stuff, but I ain't putting my neck out for anything they made in the last 4 or 5 years.
