Is there an appriciable difference between big name tools?

There are a lot of quality tools out there. Quality specialty tools is where you see the difference. Snap ring pliers for example, you get what you pay for. Lifetime warranty means nothing if the tool isnt up to the task. I make my living with my tools,and since i went self-employed i have been replacing some tools with better quality stuff. But Snap-On rolls right up my driveway.
