From a "technical" point of view, the fighter wasn't *COMPLETELY* out and the other guy started walking away.
So, from that PoV, the fight could have continued.
However, Reem went stiff for a moment as he was *still* falling down. There was a highway-like opening for a punch that could easily have KOed him into Oblivion (Think Ngannou x99999)
That, plus the fact the cut was so bad, makes this a perfect stoppage.
So, just to "remain objective", though I really shouldn't when you think about it, I voted "Very good".
EDIT: Honestly, I know everyone has a different opinion and I respect that and to each his own, but I must say this topic is a perfect example of human delusion
