With my first dog, Kai, I trained with a slip collar. Kaedyn was with primarily corrections as well. When Keeva came along, I trained with positive methods. Leash corrections and positive reinforcement both worked for my dogs and all three listen reliably. I don't think there is a right or wrong way to train a dog but my preferred method is positive reinforcement. The enthusiasm I get from Keeva (positive reinforcement) and Kai & Kaedyn (leash corrections) is huge. And Keeva loves to learn - she offers me new behaviors in order to get a click. It makes training much easier for me.
