Women are just more visually appealing. Regardless of body type, they can be thin/chunky, short/tall, they're usually pretty nice to look at and it's rare for me to see a girl that I find to be visually unattractive.

I'm not saying this from a romantic/sexual sense either, just as a general thing. A lot of straight women that I have talked to have agreed as well. Even though they're sexually attracted to men, they would often find women more visually appealing.
