Thinking he's a bad writer is an opinion, it doesn't really need evidence.
For example, I have no doubt that if Gatiss was showrunner, he wouldn't necessarily run Who into the ground, I'm sure it would continue to be a success.
But as I've not enjoyed a single episode of Who he's produced beyond: "eh, that was alright", then I have absolutely no desire to see him as showrunner. He's written eight episodes of Who now, I'd say that's a large enough sample size to come to a conclusion about someone's personal writing preferences.
I'm sure someone could do an AI or IMDB or something comparison of his episodes compared with the average but IMHO a Gatiss run Doctor Who is not a Doctor Who I'm interested in.
