There's just very little overlap in sensible use cases, they barely even count as competitors.
Unreal, of course, has more features and is more powerful.
Choosing Godot means you are more likely to actually finish making the game. Choosing Unreal means you can potentially make a better game. For me, that's a tough choice, and I often have trouble deciding between one and the other (for 3d games)
There is a vocal amount of people (can't say whether they're a minority or not) that tout/desire the major open source engines to be a valid replacement to the commercial ones. This is also happening in Rust, where Bevy is extremely hyped.
So, while it's absolutely true that comparisons don't make much sense, practically, there is a lot of talk about such comparison, so it does make much sense to make this very clear, at least in order to inform developers.
