Verdict
For concept and key art on a subscription; you own what you make on any plan, but studios over US$1M a year need Pro or Mega, and images are public unless you pay for Stealth.
For game-ready props from editable templates with Unity/Unreal plugins, plus rigging, retexturing and image tools on the same plan; the free plan is personal-use only.
