You should also keep your UV ISLANDS straight, even if this will cost a bit of distortion. If you noticed on this video, he cut every circle and create a rectangle from it. It's not only to make more space on your UV, but it will make a better bake.
For those using blender, there are a couple of commands to make this easier. If you have "space" set to search, you can -- in edge mode -- select sharp edges and determine the angle. This allows you to select your hard edges. Then mark then as UVs. Then you start removing UV edges that don't work as well. It's easier more easier to work backwards then forwards.
Then, if you want to make sure you're not going to get distortion, head over to a UV window. Click the drop down box for overlays, then click "mesh distortion." Add cuts where needed. Rememvber that your unwraps will look better if you have supporting edgeloops for your booleans, as well as triangulating areas that you have holes in.
Finally, get a free or paid asset to pack your UVs with a proper algo. Blender's vanilla one suck. Just get a new one.
Thanks for this
thank you a lot ♥
I get problems in normal maps where some flat surfaces are soo white and dark purple...mostly in hard edges...what are the solutions for that and can you make a video on them..plus a video on multiple udims baking strategy with multiple materials on it...baking for a single model....thanks in advance 😊
For multi udim baking this should help:

isn't it necessary to have a good uv map for the low poly ? and should the high poly also be uvunwrapped ?
You don't have to unwrap high poly for baking. High poly is just a shape which you want to transfer to low poly as normal map. Imagine that normal map is a ghost of the high poly transferred to low poly. But sometimes you need to unwrap high poly, for example if you want to add some details in ZBrush, like pattern, or text. Then it's needed, but you are doing this only for adding the detail in ZBrush. When you export the high poly from ZBrush for baking, you don't need UV mapping anymore. Also it's worth to create real high poly in ZBrush, for example "knurling", or text, because if you have "real" detail on your model, it will create very realistic bake. If you want add "knurling" in Substance Painter with height map or normal map, it is possible, but quality of it will not be that good, as sculpted in ZBrush.
for baking low poly with high, good means to cut each hard surfaces.. and you don't need to uv high poly.

What a useless solution. Just dont use hard edges. or use it only at extreme angles. more uv islands = less usefull uv space
If you want to have a realistic model, then your solution is best, but if you want a stylized model, the video's solution would be better.
