Who ever considered free graphics design tools bad have no experience with using GIMP. There's nothing you can't do on GIMP. I'm not trying to discredit premium tools but there are so many good free tools which get job done 100%.
Free tools can never been said to be bad. This is because they equally get the job done 100% perfect. For example, Canva and GIMP are free too but they can do any graphics jobs they work on decently.
