Not wanting to turn this into a lengthy debate over ad-blockers, but I tend to leave it switched on by default and make an exception for sites I visit regularly, value the content of and which don't go nuts with adverts. I find them fairly useful sometimes and even bought things advertised on these sites in the past. I use it for technical rather than aesthetic reasons much of the time - a line was crossed when Flash ads started autoplaying videos. Suddenly, a significant proportion of my fairly meagre CPU was being used to show me film trailers or mobile phone adverts rather than for my own uses.
