I mainly do work indoors, so the brightness does not really matter that much to me. But as far as I can tell, the brightness is pretty normal for laptops - I don't think it's any brighter or dimmer than other laptops I've used in the past. According to this website that I found, brightness is 25 to 486 nits. Google search seems to say that average maximum brightness for laptops is somewhere around 300-400 nits.
My understanding is that the screen is generally what eats up most of the battery on device, so if you plan to have brightness turned up, it might be difficult to find a laptop with a long battery life.
The Thing (1982) has basically consistently been my favorite horror movie
