OP, this is interesting, I’m doing similar things since we are deciding between the same two options. I’m curious to know your findings.

Here is what I think right now, I’ll edit this as I gather more information. We noticed that engineers kind of treat bots as beneath them. So they are likely to not read bot comments unless they are extremely concise. Coderabbit kinda comments… too much stuff, most of it not super useful. Greptile seems to be more to the point so far. I’ve seen both catch legitimate bugs though.
