Frankly, I would have loved either as the Doctor. That's not to say that I didn't love Gatwa, but I can definitely envision Stephens or Bernard, just as I could envision Ben Daniels, Capaldi's runner-up, as the Doctor.
Haven't seen much of Daniels outside of Law & Order UK (and as Herod in a production of Jesus Christ Superstar recorded live for tv a few years back) and after reading that he'd been in the mix losing out to Capaldi wished we'd gotten the chance to see him as the Doctor.
As Daniels is openly gay, I wonder if we would have seen the some of the comments directed towards the show because of Gatwa being queer or whether it's simply a sad sign of the times.
