Gurl don't lie, Season 1-3 were probably the best. I liked Season 4, 5-8 had there moments but they weren't as solid beginning to end like 1-3 were. (albeit theres like a handful of episodes from those seasons I never watched or don't remember much about so season 6 could certainly rise higer)
And Prue has always been the most powerful witch. Bitch was a boss and could reflect and toss them demons to the side like nothing. She could also project herself to other places, extremely helpful, once she died it was Piper. Phoebe was powerful as well but I felt like they exaggerated her powers cuz from season 1-4 she was basically useless, what are you gonna do when demons attack, levitate and have a flashback?! Lol. Plus never seemed like team leader, she can't really carry a scene on her own.
