Best 3 rd party .FBX viewer

For the first look, I always use Microsofts integrated "3D Viewer". (App is called 3D Viewer)

Later in the project, I like to use Unreal Engine 4 (currently sometimes Unreal Engine 5) because it is fast and reliable.
I do not need to install all options of Unreal Engine 4, only the core version. No Editor Symbols, Starter Content and so on.

I do not know if you have the space for around 18 GB of core components. (I often use it. For me, it makes no difference.)

Perhaps Blenders EEVEE and Cycles as Render Engines for comparison.

Thanks

DEEP EXPLORATION.
100% and definitive the end-solution.

Thanks a lot
