It's often assumed that anything free is inferior, but this goes beyond the realm of mere assumptions of capability.
Take Inkscape for instance. Professionals can and do use it. I use it. Okay, maybe I'm a little biased about my own self here 😉.
But the point stands. Inkscape doesn't lack capability. If you're using it for what it can do (and does very well, I might add), you'll come away satisfied. So will your clients, or company, or whoever depends on you to depend on it to get results.
