I don't really wanna touch Adobe stuff (and I'm not sure if it works in Wine). In a lot of ways I think it does things better than designer too! The spot that seems the sorest to me is painting textures. It overall does the job tho!ģD graphics are a slightly mixed bag: the main ingredient, Blender, is amazing! Equally amazing is Material Maker, which a lot more people should hear about, which lets you procedurally create materials, akin to Substance Designer. Thankfully this time the alternative is much better! Inkscape is a pretty competent program, though it does have a few very confusingly lacking features.
I do vector art sometimes, and the situation is similar since I used Affinity Designer before. For now I've just been using Krita for that, but it's not really suited for things that aren't drawing. GIMP is unfortunately pretty awful, so that's out too. I was using Affinity Photo for that, but Wine doesn't like it for now, so I gotta use something else. When it comes to general image editing, it's a bit less flawless. My primary thing is drawing, and that goes flawlessly! I was already using Krita with some Blender here and there, so the transition was seamless - just straight up getting the same software and using it the same way.
and it's been pretty alright! Here's a small breakdown of my experience so far if you're curious about it, or maybe in a similar situation.
