I will bring a few sources to make the point…
On the one hand, supporting ugly, we have the Gemara (Nedarim 50b)
The Emperor's daughter said to Rabbi Yehoshua ben Chananya: ‘Such beautiful wisdom in an ugly vessel!’ [referring to his appearance]. He replied ‘Learn from your father's palace. In what is the wine stored?’ ‘In earthenware jars.’ she answered. ‘The whole world uses earthenware vessels! And you – the Royal family – also use earthenware vessels!? You should store it in vessels of silver and gold’ So she went and had the wine replaced in vessels of gold and silver, and it turned sour. He said “the Torah is just the same. It is best preserved in me because I am ugly." "But there are handsome men who are learned!" she protested. "If they were ugly," Rabbi Yehoshua replied, "they would be even more learned."
and Mishlei 31:30
beauty is vain (hevel hayofi)
On the other hand, supporting beautiful, we have Bereishit 10:11, Bereishit 29:17, Bereishit 39:6 stating the beauty of Sarai, Rachel, and Yosef respectively.
Also the Talmud (Brachot 20a, Bava Metzia 84a) describes the beauty of Rabbi Yochanan in a good light.
Which is better for ones spiritual development and/or connection with Hashem?
