The toyo's I liked most are the open country r/t's. I had the open country m/t's before, and they were pretty quiet for how aggressive they were as well though. I had the a/t2's and they were surprisingly about as loud as the m/t's. Personally I think if you want aggressive, the toyo's m/t is about the same noise level as the a/t2. I haven't tried the a/t3, they're new and I think I'm settled on r/t's and m/t's.
Personally, I think the r/t looks a little more aggressive than the a/t line from Toyo. Plus the r/t is hardly noticeable on noise level, they are quieter than the factory good year wrangler c-rated, not sure about the passenger tire that come on our trucks from the factory though. I only had them for about two weeks, and didn't pay attention to the noise.
