Monaverse
Monaverse seems to focus an artists as the language used on site insinuates throughout the UI. If you want to create on the platform, you will immediatey face a steep learning curve because you cannot just drop in a .glb file or simply import a vrm avatar. You will need to provide special Unity files, a specific video preview for your space and there file size limitations that really make your life difficult. The beauty of some of the worlds that can be explored with a default avatar are something special. Once in a world you can also load a Ready Player Me avatar which is a pleasant surprise. Apparently you can also load a hosted VRM file into the platform.
