Your first problem is you're using a Mac. But beyond the obvious trolling, Krita excels at painting and is getting better at text as well -so far text tools have left to be desired but they've been working on a revamp for some years now, probably coming rather soon. What I find lacking as a daily user (I do illustration in Krita, animation in Blender) is the general image manipulation tools. Transforming, snapping, transform masks... are often either lacking in flexibility or poorly performing. I use Affinity Publisher on the side for compositing my illustrations with text for print or web, I wouldn't be able to rely on just Krita for that. But for painting, it's absolutely fantastic -performance wise, usability-wise, the shortcuts are so well thought out it's a joy to use. It's really made with painting in mind. If you like using filters, they have a good G'mic integration with hundreds of builtin filters. I can't comment on their mac builds though, you'd have to try them yourself.
