My two cents regarding this subject:

Right now, ZBrush is slowly being caught up by Blender's Sculpt Mode being supercharged by a gifted Spanish developer, but ZBrush still wins when it comes to a consistent, unified workflow, high-polygon sculpting, quad auto-retopology and more.

When it comes to polygon (subdivision) modeling, I tried Maya a few years ago, and think it's dated and bloated compared to Blender. 3ds Max likewise, although I've got the impression that Max is making a slight comeback lately. For example, they've integrated a really good quad auto-retopologizer that's comparable to ZRemesher / Quad Remesher, and they recently introduced an affordable Indie subscription. Too bad Max is still not available for macOS though.

I'm not a fan of Blender wanting to be everything, including a full-fledged 2D animation tool and video editor. Right now they're focusing on Geometry Nodes (procedural modeling with nodes), going for the Houdini users.

Just about the only area where Blender still really sucks is NURBS. That's why I think there will remain a place for MoI as a complementary tool next to Blender.

Michael, you might want to consider embracing the rapidly growing Blender community by integrating a bridge between MoI and Blender. I would surely welcome that, and promote it in the Blender community.
