Some people prefer PHB ability rules. Some Tasha. They each have their objective pros and cons and subjective aspects as well.
What is in retail BG3 is neither, and most probably agree is lesser for it. Though it has some quirks (like human armor prof.) that can be exploited in some builds that people may dig.
That said, the OP expressed his opinion and has the self awareness not to demand Larian force a change on everybody that prefers the current implementation, but to give the OPTION to revert to PHB like rules to those that wish to take that option.
In a game that promotes player choice, it is a fantastic idea. Put a checkbox on the options menu and let the player decide what is a more fun experience.
Win win.
