Well...to be honest, in an LV forum where the majority of us do have Mono and Damier items, I don't think it'll be really easy to find many people who dislike these lines.
These two lines are the very basis of LV, without them, LV wouldn't exist. Plus, they're great everyday lines, they match just about anything and are durable. Also, $600 for even a basic bag is still a lot so it's really not about the "cheaper" price point, especially nowadays
I agree, and the mono. and damier have such a long history. There are few things that have stood the test of time like that!
They are the very definition of LV, and are recognised all over the globe, both for good taste and quality! To dislike them is, in my opinion, to dislike LV!
