Perhaps not surprisingly there's a just as large cohort of people who love how GUIs are defined in desktop and mobile applications and despise CSS. I've seen someone go so far as to redefine the entire browser rendering system, drawing every button and control onto one big HTML canvas element. They're very different ways of building a UI, and it's hard to find people with a ton of experience in both to provide perspective, much less an answer as to which is 'better'.
