Persona 5 Waifu ranked by how commonly people choose them, using the most iconic choice in video games for comparison. This is based entirely on what I’ve personally seen online, so your mileage may vary.
(Ironically I’m a Bulbasaur guy and I picked Makoto)
UPDATE- Before I made this I had never seen a single person say they wanted Ryuji as their waifu, and now I’ve got like eleventy squillion people yelling “WHeReS RyUJi!?” at me (and, like, five people complaining about the lack of Akechi). So, never let it be said that Art Guy Charlie doesn’t aim to please because Ryuji and Goro have now been added to the Mew Tier.
