I hate all CSS frameworks but in real life all is about efficiency. Projects need to be done, there are deadlines. If you can do what is on the mockup with framework and that will make your task faster - why not? Of course if you will get a website mockup which will need custom solution - you will have to use CSS and make it this way. I think we need to work the way is best for us. That's why I don't tell anybody to not use a frameworks or work only with vanilla CSS because this is not my business
I usually use Bootstrap for finish my projects fast. Then, no complain from clients. No problem.
