elements of argument

Recently I was producing music with Andy who is a friend of mine, who has always been a very talented musician but just started to getting in to the production side of it and he use’s Pro Tools 8 to produce his music, but we were at my house and I use Logic 9 Pro. So as the session progressed he kept pointing out reasons why Pro Tools 8 is way better then Logic 9, And the first claim he presented was that Pro Tools is much better because the lay out was much easier to work with and everything was right where it needed to be. So I quickly replied stating that’s clearly just a preference because I feel the same way about Logic. After I said that he quickly replied with an ignorant tone well there’s a reason why Pro Tools is the industry standard, making the assumption that just because it’s the industry standard it makes it better then all other recording software. So I mentioned although its considered the industry standard, I believe logic is better for the creative side of making music, while Pro Tools is better for the recording and editing. Which I believe strengthened my argument because at the time we were making music not recording it, so I believe developed some creditability for my argument because i had a understanding what Pro Tools was capable of and what Logic was capable of so it showed I had some knowledge of both programs. So as the argument continued we both kept giving reason why we believe one was better then the other, but now looking back on the argument we were both just defending ourselves and what program we use, with hardly any evidence and mainly just reason why we prefer that program. And nether of us ever really establish much credibility  because nether of us really knew to much about the other program, so that was a huge weakness in both of our arguments.
