Fast drying screed price / experiences?

I have a question again. As I already wrote, our construction start is being delayed. Our company wants to make up some time so that we can move in by late summer / autumn. Quick-drying screed is to be used. The construction company will cover the costs. Does anyone have experience with this screed? The construction time is shortened by 4-6 weeks because this screed dries in 3-4 days. Are there any disadvantages?
Thank you very much for your helpful answers!

Which floor coverings are planned?

We have this screed in the house. As laymen, we could not see any disadvantages. The screed is more expensive and contains chemical stuff so that it sets faster. In our case, it did not crack. So apart from the price, according to the screed layer's statement, no disadvantages.

Tiles and laminate are planned.

Thank you for the response. I also read about the chemicals and that they supposedly do not cause illness.
