i wanted to know the main difference between theese 2 entities

i tryed to cut the area with lots of hint brush

don't know which is the best suited in this situation

func_detail is just that, a brush detail that does not split vis leaves.
func_brush adds options that allow you to manipulate the brush (toggling it on or off, disabling shadows, and so on...).

func_detail is not entity in regular means. After compile it becomes as brush. It's a brush that doesn't affect visibility calculations and does not seal map from black void. Use it for non-sealing structure and that doesn't affect visibility much.

func_brush is an entity. Basic functions are toggling on/off.

You mention hint brush, and you seems to assume they are func_brush, but as other pointed out, a func_brush is an entity.

Hint brushes are world brush textured with tools/skip, and tools/hint on the face you need.

To optimise a map, the first step is func_detail. They are ignored by vvis, so every small brush that doesnt block visibility should be one. But also the brushes with complex shapes (cylinder, brush with more than 6 faces)
Using hint brushes is the second step, that is done ONLY after you correctly func_detailled. their goal is to improve the visibility created by vvis (rendering less stuff that you cant actually see from your position) to get better fps.
