I prefer Borla to all the rest , a matter of personal preference. I started out with the Borla S and switched to the ATAK. People on this site indicated the ATAK was too loud and I bought into it but its not true. But again I have a 2016 GT350, a 2018 Hellcat and a 2008 Will Cooksey Z06 so its all relative. our ST's are only 3.0 L and twin turbos, the turbos inherently quieten the exhaust note so in my opinion the Borla ATAK brings a throaty sound back into it. Its like a good tequila and all subject to personal opinion.
