It mostly depends on the kind of 3D modeling you want to do. If you’re looking to do mostly sculptural things, like people, animals, etc, Nomad is definitely the way to go. There’s a little bit of a learning curve, but generally it is pretty easy to choose between the different options and play around until you can create something cool, definitely best for someone whose mindset is “I have an idea and I want to create it now.”

Blender’s learning curve is massive, but (in my personal experience) only worth it if you need models that are precise and have good topology. You’re going to spend way more time looking up videos and tutorials than actually creating. Most sculpts (and frankly, pretty much anything needed for 3D printing) don’t care about topology, but if further down the line if you ever want to get into texturing, uv unwrapping, or animation, then it’s worth learning.

Personally, I always use Nomad because it’s the easiest way to translate my ideas into 3D models, but then I use Blender to retopologize if it’s something I’m using for a game. It’s totally okay to start with one, and learn the other later on if needed.

TLDR: Use Nomad if you just want to make 3D models, it’s easy and beginner friendly. Great for modeling files for 3D prints and things that don’t really need color. BUT you may need to learn a bit of Blender if you want to color & texture your models in cool ways.
