We recently scrapped our old Bootstrap-like framework too, and also opted out of using any type of UI widget tooling. Everything can be done so much more easily today with vanilla CSS and JS that it's hard to justify the overhead despite knowing there'll be a certain amount of customization work required to implement a good UI. Still using a CSS preprocessor though, like you, but soon that will probably be gone too.
