Hmm. I wonder why this seems so. I can come up with two points that might contribute to this impression.
Bending and twisting renpy to do things needed for a point & click are possible but quality might suffer, because the engine is optimised for other things. Also the tag point and click might be misapplied, because technically you point and click in most games that can be played with a mouse.
And renpy is used by many hobby developers with less experience in coding. So the average level of professionalism might be lower, which might be also visible in the usage of assets and "quality".
Overall I would assume that godot is more suited for a general purpose 2d game. The vast majority of the point and click renpy games do tag visual novel as well...
