We debated this a couple years ago. Everything I wrote then is still true. Both macOS and Aldente change the target battery percentage in the SMC key, and then the low level system and the hardware do the hard work of adjusting the voltage in either case. macOS uses their adaptive machine learning to set the SMC key target and Aldente lets you set the target manually. Whichever is best for your battery depends on how you use the computer and how well macOS is able to predict that.
