I'd mostly agree with you. If you're spending the money and looking for a specific engine performance or max performance, more than likely the answer is a custom grind. For mild builds or on occasion when an off the shelf cam will meet your specific needs they are ok.
I'm not sure why you dislike comp cams. My new engine has a custom comp cam. Nothing wrong with it and if IQ trusts them, so do I. If you've had bad experiences I understand. I stay clear of Crane stuff now after having major issues with their gold race rockers on an engine.
