I keep ublock on all the time except on some sites. Sometimes, there is a worthy ad (e.g. one month free audible, cause I visited the site). I don't resent ads, I am totally fine with them, and if they help sustain some site I use, I am happy. The problem is when they are taking over the whole experience.
