[LAU] Ambisonics: Which order fits my project?

Hi! Speaking about Ambisonics, I have one question regarding the different orders you might want to use, which I couldn't found to be answered in the (not too much) media I read and watched about this topic: Which border do I have to reach in my project that I should consider switching to higher (second, third or more) order ambisonics? Is it the number of output channels? Or is it: Always use the highest order you can afford? According to this video <https://www.youtube.com/watch?v=f4oE3i2tjyA>(, which I haven't watched the whole length,) at 23:14 ff it's about frequency response and compensation - and there it seems to be better using lower order. It would be interesting making a direct comparison between first and third order to hear if it's worthwhile. But without the equipment… So, this question goes to the pros (hoping not to start a flamewar…) There is another video <https://www.youtube.com/watch?v=kFuKaKbfxls> I found. Without ever being able to hear higher order ambisonics I wonder if such things as fifth order is more or less something like "look, what I can do" comparing the time and effort with the actual improvement in audio quality… Sorry, if I step on someone's feet… Greets!
