I wouldn't say its fanatical - you just happen to like pro tools, and as a trainer, you are entitled to express your opinion. I am not a trainer, however, I have used Pro Tools for a while but come from a different background. As an HD user, I see the benefits of Pro Tools and it was one of the reasons I got it in the first place, the most important being being able to accomodate my session files from different studios to my home setup. However, Pro Tools is not the one all end all as exemplified by other daw users, namely in Europe, who do not use Pro Tools as a standard but still recognize it as a major working format. I have had projects ship from Germany in the native Nuendo format and, to this day, a majority of my European collaborations remain largely Steinberg centered. Is it lesser of a choice? Nope. IN fact, its just as good. The way I see it, the freedom that you get to mix and match, regardless of the propritary hardware that PT imposes on its customers, can be seen as a blessing or a bane. There are more than enough thirdparty companies that offer great conversion quality for audio that equals PT in terms of quality, RME and Apogee being a couple.
Nevertheless, the use of PT in large scale productions does not mean it is the best - Hans Zimmer, a devoted Steinberg user continues to score music to this day on Steinberg products and his non-PT approach certainly does not make him any less of a stellar artist. The point? As long as you know how to manage your gear, and direct workflow latency becomes less of a problem. It is common sense to tread lightly when technological limitations do not offer you as much bandwidth as you want, and this is what sets good DAW users apart from fledgling ones - they KNOW how to exploit the strengths and benefits of their gear whether it is PT or not.
From experience, PT is great - hell, it ought to be for the amount of investment you put into it. Do I have complaints with Digidesign? Nah - as long as I keep working on projects and things work well, I am a happy customer. But as a DAW user on the PT and non-PT end, it really doesn't matter in the end because it all matters on how YOU - the user - end up recording your music.
