In my time managing interior design projects, I've found that, usually, it's not the interior designer who has the strongest opinions on which are the best paint brands, it's the decorators. I've had conversations with trades on site where they've refused to use certain paints to complete a project, instead asking for them to be color-matched.
For the uninitiated, your choice of paint brand might come down to one of a few factors: most likely cost; perhaps a particular color you've seen and want to recreate; or the value of a luxury name. However, once you've lived through a few paint jobs, you'll come to look for other qualities in your paint brand of choice.
