what is the best open source program for illustration in your opinion? i don't know if i choose gimp, krita, inkscape etc.

I usually use cracked Photoshop, but it is very difficult to do that and I would like to use one of these open source software, but there are so many that I don't really know which one to choose, I would like the best possible. any indication? Do you know any that are very good, but few people speak? because I always hear about them
