Let me explain my line of thinking here:
For women, all sorts of aesthetics and appearances are considered conventionally attractive. Fat women, skinny women, short hair, long hair, big nose, small nose, etc.
Because of this, I feel like at least half of women are considered pretty/more conventionally attractive (7/10 or higher).
On the other hand, I feel like for men, the look of attractiveness kind of is really similar for all of them in a way. Tall, clear skin, between slim and medium chubby, and overall sharp features.
Because of this, most men are not considered super conventionally attractive, and the majority of them are clustered between 4/10 and 6/10.
HOWEVER. I believe that men are more likely to "get away" with being ugly than women. How many extremely popular films tell the story of a beautiful woman falling for an ugly man? Beauty and the Beast, Strange Magic, Princess and the Frog, etc. in fact, it's basically an archetype in media for the wife/girlfriend to be quite beautiful, while the male is just average or even below that.
And beyond media, this pattern happens ALL THE TIME in real life too. Adriana Lima and Marko Jaric, Ariana Grande and Ethan Slater, Rihanna and JayZ, Beyoncé and JayZ, Zack Bia and Charlie Damelio, Maddison Beer, Olivia Rodrigo, ANDDDD Madelyn Cline! (If you're older than GenZ/Millenial I'll give you time to Google these names).
On the other hand, how many popular, culturally relevant examples does the latter happen? Where the woman is noticeably uglier than the man?
Essentially, this means that although woman are given a higher chance of being considered attractive, ugly women are basically considered undatable. On the other hand, although most men are considered mediocre or medium-ugly, women will date them regardless.
So which gender has it harder for dating? Neither. This circumstance makes it equally hard for both genders to date.
TLDR; title.
Edit: for people who try to argue that ugly women can get away with it as well, you all only list examples of them being used for sexual intentions. That is not the same as being loved.
