A number one R&B album debut is real, and I won't wave it off. But the R&B albums chart is a small pond, and a debut week is a fanbase showing up, not a catalog winning. The question isn't whether Donell had a pulse in 2006. It's whose records get the biggest reaction in the room, and that's still Joe.
Notice the argument keeps migrating to categories. Writing credit. Chart trivia. Longevity measured in years. All fair-ish, none of it the scoreboard. Line the songs up. I Wanna Know against Where I Wanna Be. Stutter against U Know What's Up. Joe's records hit pop and R&B, stayed on radio longer, and crossed over further. Donell wrote his own lane, absolutely, and that deserves respect. But you don't win a versus battle with liner notes. You win it when the crowd drowns out the track. That's Joe's catalog, not Donell's.
