AAlhosainidon't invest time/effort in it, because Autodesk has stopped MCG dev since version 2018, so they've made the decision for you...no morevusta
if you most likely just want to create static geos..well then just get Apprentice and take it for a spin...absolutely nothing to lose except your time...but you HAVE to pay that way.
I've done enough MCGs to know that Houdini is far more flexible
doing stuff like this with MCG will not leave you with much hair left...
speaking about FREE...Blender 2.93 are going nodal too...I can see already it's way better than MCG but not at Houdini's maturity yet (obviously) why not take Blender out for a spin too ?
I respect MCG surely, but still no much learning recourses available. Houdini is the master of the proceduralism, with the ability to combine your geo with a robust fluid dynamics effects, fractals, L-trees, Vex..etc, which are missing in the other 3d platforms like Max.
I really envoy Blender community for the continues developing they get, but still going to blender means you should re-learn many aspects you have already mastered in Max for instance, and you need time to get used to it, and to practice it.
other nodal max plugins are popping up so maybe nodes in max is not quite dead, just maybe MCG took the wrong path.
