I like the origins, so this is a big ole shrug from me.
Until a game developer actually gets to the point where a custom character is fully-voiced and has a massive questionnaire attached to character creation that will dictate what I'm likely to do in different situations and how I feel about certain ideologies, an origin character will always be my go-to because I'd rather have a complete experience with a dedicated personality that's set in stone. The idea of "Tav" awkwardly emoting or only choosing from oversimplified options throughout the adventure is terribly boring to me.
A game developer would need to partner with someone like eHarmony and come up with some 300 question survey and include an MBTI test in order to have a custom character feel like they're of any consequence to the world.
They would not need to do a survey.
I personally don't care about the voice acting.
That is not to say the voice actors don't do a good job. They do.
