I'm glad you found a satisfactory answer here! But I'm also surprised that no one has directly countered your assertion that knots are ugly. The answer is very subjective to the person, of course, but I also suspect that there exists somewhere a knot you'll openly wear with pride once you discover it.
Knots can be dazzlingly gorgeous, elegantly refined, or prosaic and utilitarian. Look up the group Mateloteurs on facebook for examples of the first two!
