I used Corel Draw back when I worked at a T-shirt and jersey shop in college, and frequently used it to drive a vinyl cutter for jersey numbers and other decoration. From anecdotes I’ve read since then, it appears the software is still the preferred choice in custom apparel, signage, and vehicle livery shops because it interfaces well with the cutting machines those industries use.

Corel Painter has its niche among digital artists - it's still one of the higher end digital painting programs that simulates real life mediums (acrylic, oil, watercolor) remarkably well.

There's really no iPad equivalent to Corel Painter, but Corel registered the procreate.com domain to redirect to their Painter product page (Procreate (procreate.art) by the Australian company Savage is one of the strongest digital art applications on the iPad).

Corel has also recently purchased Gravit Designer, which presumably will stand as their main digital design app that competes with Sketch and Adobe XD.

Other than Photoshop, what are the favorites these days?
