Marco,

i know that you are a beginner when it comes to renderings and you are no expert,
but you should think more often prior you post your articles …

In the hand of talented Blender Artists Eevee can render nicely made images,
in a fraction of time which made also clients happy.

One example for you to learn:

And one example an Blender Artist made for a client:

And if you google:

https://www.google.com/search?q=Eevee+Interior+renderings&tbm=isch&source=hp&sa=X&ved=2ahUKEwixjd31ov_gAhUmwcQBHQBiC8gQsAR6BAgAEAE&biw=1196&bih=958

Maybe if you purchase the Eevee course from Chipp you can also archive photorealistic
renderings with Eevee … :-)

Regarding Cycles render times, this is also nonsense what you post. You maybe are used
to ray tracers and not path tracers (which Cycles is). Metin has posted the Denoiser link,
so you can render in a fraction of time too if you use the denoiser and set Cycles to lower
samples.

Stefan
