pixel art is the least enjoyable for me.
Also I myself can neither code nor draw. Both are skills I highly appreciate. That doesn't mean I only want hand drawn art or code.
In the case of hentai games the average quality is pretty low, with some really good games standing out but also lots of trash. So at least make the trash more easy on the eyes. But not every game with ai art is trash.
In the end it all comes down to personal taste.
