Except that I like what he did with Doctor Who, aside from the time the pandemic kicked in and made things a lot more difficult, which affected a lot more shows than Doctor Who. I watched the last episode of season 4 of Unforgotten last night then read how much Covid affected it; it would have been significantly different. And that's just a modern day cop show that's got to be a lot easier to make. I don't think it's fair to assess Chibnall as a Doctor Who showrunner after his second series because no one else in the show's history faced challenges like he did. Hell, even after Covid started, he did "Eve of the Daleks," which I quite enjoyed.
Read my post again. It's not just about popularity, it's about actual achievement and respect from his peers.
Edited to add: if you want to point out that Chibnall wrote the utterly crap "Cyberwoman" episode of Torchwood, well, yeah, he did. But he also wrote the really, really good and devastating Torchwood episode "Adrift," which more than balances that out.
