Default Alignment Type

Sorry again about my questions that are very basic, but if I ask them means I haven't found any "reasonable" answer to my questions.
So ... what about different alignment types (Bessel, Butterworth, ...) and order (second, third, ...).
Up to now everything seems to me "magic" or simply matter of opinion.
That is, when I take into account a driver characteristics, what is the "best" choice ? By "best" I mean "under some circumstancies".
But what ?
I don't fear mathemathics (I'm a theoretical physicist).
Thanks

The simplest explanation is that they are pretty much
the same thing with varying Q factors, Thompson having the
lowest and Chebyshev the highest, with Bessel and Butterworth
in between.

As a theoretical physicist, I believe you have got all the formulas. But if you don't have experience with working with speaker drivers, then the answer is that those formulas (even the small thiele parameters) do not answer MANY of drivers' behaviours in reproducing sound.

Default So, ... it's magic ?

Being serius: no, I haven't got all the "serius" material on x-over design on the net.
Anyone has some pointers ?
When dealing with Zobel networks and all that I've found very valuable the work done by Prof. Leech.
By the way: I have written an Excel sheet that automates (with very good results) all its calculations.
Thanks
