GR has big focus on crossover parts and overall build quality which is a perfectly legit focus to have. There is also a focus on measuring results. Of course in the end build quality alone does not assure a good design nor good sound.
Whereas ASR prime focus is measurements. They might mention build quality but if it does not measure well it wont get the seal of approval.
I have learned a lot from both. It need not be a competition, or one versus the other. Different perspectives yield superior viewpoints in the end.
