Very unique tool that can really help save you in a pinch when your kick fundamental isn’t where you want it to hit or doesn’t have enough sustain or you want to add some subharmonics to a bass. It’s definitely a ‘with great power comes great responsibility’ sort of thing as it is easy to overdo it, but with the right listening environment and compression scheme this plugin is really capable of giving you the serious and tight low-end and sub frequencies that separate good from exceptional low end. UA got it right and having the native option really helps give flexibility for UAD- vs CPU-based processing which helps manage latency while tracking depending on your DAW and hardware.
