I brought my 2019 GMC Sierra 1500 SLT crew cab in for service, and got a 2020 Chevrolet RST Z71 extended cab as a loaner. The loaner had the Bose system. There was no noticeable difference between the clarity as compared to my non-Bose factory system. The only difference I found was that there was more bass, I guess due to the subwoofer, but it wasn't the punchy bass I tend to associate with a sub. Just kind of a muddy bass sound, not that different from what you get if you turn up the bass on the factory non-Bose system.
