Adobe Illustrator appears to be the standard in almost any creative industry. I have not used it. If you work for a company that is footing the monthly bill for Ai, high five, that is awesome. But for me, that is going to cost another 25-50 dollars a month. And while that doesn’t sound like a terribly large amount of money, I don’t need another monthly expense.
An alternative (especially for those of us who don’t have a need for every Ai feature) is Affinity Designer.
