I played Origins a few times, it remains my favorite and I acknowledge that other people like different things. I liked how the origin story gave you a completely unique voice. When I talk to my friends who've played it (and there are many) none of them remember a silent protagonist, most took some serious reminding before they'll admit that The Warden didn't talk.
Having a good voice actor (Jennifer Hale) makes one kind of charecter; for Mass Effect I can't imagine having a silent protagonist. But I also would never have have the versatility of storytelling I did in origins if I'd been forced to deal with what my character sounded like.
I played an elven mage in DAI, I was loyal to my own gods, fought for elf rights and generally copped an attitude with anyone who didn't like it. It was a fun and unique character, flawed yet strong and could easily have been totally lame if I'd been locked into a way of being. If we are going to get voiced parts for every game to come, they have to have the option for nuance and motivations or I'm not going to keep coming back.
An rpg lets you play a role, a good rpg makes that role fun to play, a great rpg lets you choose that role and make it your own.
