The Godot Engine team recently posted about more issues with "AI slop", including various pull requests that have become a big drain on resources.
You've likely seen other projects talking about this across the net, because AI agents and people who use various generative AI tools are generating code and submitting it to lots of projects to pump up their numbers - often while having no clue what the code does and not even testing it. This is becoming a bigger problem as time goes on.
I'm biased but I would say unreal has been a "bad engine" (still better than unity regardless of parent company) because it encourages bloat and is bloated. Is it really that good once you remove it's graphics fidelity? (Genuine question because I abandoned it before deep diving into it) We really need to go back to the roots of lightweight and optimized "apps" such as Godot.
