Yeah it is. You like deathstrole so you are defending him but in comics it is all about popularity. Same idea why Batman is even in the same league as the justice league or why green arrow regularly beats any opponent with a gun. Firestrom is dc most powerful hero but he gets beat by. Dude with a sword.So by your logic powers don't matter its all about popularity. Which really means how the writers want to portray the characters.
Read the comic and you'll see slade didn't beat him in some overpowered way. Metamorpho let his guard down and slade took advantage.
