Discount hands down.
I had a terrible experience on Sun, some of the worst customer service I have ever had in any industry. They also missed 2 nails in my tire, telling me it was a small leak and couldn't fix it. How do you miss that? (the manager will know about this employee)
Went to Discount to get my tire fixed and they were super helpful. I walked in and groaned because there were about 10 people ahead of me in line, but there were 6 different people waiting to help customers. I got out a lot faster than expected, and they were unbelievably nice.
