If you compare it to something like Mass Effect or The Witcher, it's incredibly impress. But compared to Pillars of eternity, any of the Pathfinder games, etc, it's disappointing in my opinion. At least by having a silent protagonist we can imagine our character's tone.
I am actually on the opposite spectrum from you - because I find conversation options underwhelming I am disappointed that they will not be voiced. Even a silent protagonist requires character in its writing, and I was hoping VO will fill what is lacking in written text. It’s an awkward middle ground, where I neither get a mouldable custom character, nor a compelling pre-defined one.
Having more varied voices to pick from is good though.
It's not really a middle ground, though. Whether voiced or not, bad writing is bad writing, and protags in these kinds of games tend to be just that because they're also meant to be self-inserts. That includes protags like Shepard for instance. The idea is to represent not express, kind of the way you do in a TT where at best you might have a figurine or rough drawing and need to let imagination do the rest. Actions also flesh out a character a ton too, and that's one of the strongest aids for a silent protag in a game full of choices.
That's also one reason I don't care about unvoiced protags since the writing tends to be subpar anyway. It's a lot easier to write compelling characters when you know what a character's personality is like, what their motivations and history are, etc. A blank slate is really, really hard to write and well... most games don't when it comes to self-insert protags.
