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.
I don't want to fall to bits 'cos of excess existential thought.
