This thread is like chum in the water for the RcTech community. If you support one side the other side supporters will bite you.
The biggest difference is price point right? You can get away with using the cheap toilet paper but you'll likely end up with a sore ass.
I ran a $41.23 HobbyKing 120A ESC with a Tekin SC4x 4.5. Hard to beat that price point. It may have worked forever, but I upgraded because I perceived the quality of Tekin RX8 to be higher.
