My preferences lean towards anime-esque 2D graphics but as long as the cast of characters are fun and the premise is interesting, I'm willing to at least give a game a shot. The visuals of a visual novel are a core component but so is the novel aspect. I've been pleasantly surprised by some indie works with a more western 2D artstyle in the past because of the writing.
My only major concern about 3D otomes currently is that beyond Silent Whispers which is backed by the company who made Life Makeover, none of the other Love & Deepspace copycats that were teased several months ago have teams with a games industry background and aren't interested in even making an otome game. They want to make chatbot companions that take advantage of the loneliness epidemic and just AI-generate characters that look like Sylus and others from Love & Deepspace because people already have existing attachment to said characters. It's less about the artstyle at that point, they are bad because it is slop with no real creative direction.
