I think that our "preferences" have a great deal to do with how we are built physically...especially our lips, jaw, teeth and mouth/tongue.
When I was a serious tuba player...in high school and college (I played large BBb horns and large tuba m'pces then)...I had a real preference for the lower ranges. I could play high but somehow the 2nd, 3rd and 4th partials were where I really felt at home. That's where my chops were most comfortable. But at the same time I was playing tenor trombone, and in mainstream tenor trombone m'pces those same chops felt somewhat cramped in the lower registers. I naturally gravitated towards the higher registers, even though I was playing a classic "mid-register" m'pce, a 6.5AL. This was all well before I had any understanding whatsoever about embouchure...I just played. High school, college...as an improviser I gravitated to the middle/upper ranges of the trombone but the lower ranges of the tuba.
Now I understand that my lips are fairly full...fairly fleshy...and they roll out into the tuba m'pce. That means I have a relatively heavy "reed" on tuba if you think of the chops in the same way woodwind players think of their reeds. But...in order to fit into a tenor trombone m'pce those chops have to be somewhat rolled in or else things get very crowded. So I...quite unconsciously...developed a lighter "reed" that was more efficient in the upper ranges. The task of a serious brass player is to find where he or she really lives on a given horn/m'pce system in the most natural way possible and then connect from that register up and down into the other registers.
A lifework, actually...
This goes to my "multiple settings" approach. There comes a range point (on any rim and in any direction) where the most natural way of placing your lips in and on that particular rim simply isn't going to cut it. But there are other balances that are "natural" for those other registers.
For example...with my own setup on my .500 bore horn and 11C-ish/7C-ish rim for the middle/high range (my most "natural" range on that equipment) I can hold that exact balance doing Carmine Caruso interval exercises down from there...on a cutoff rim or m'pce buzzing this becomes really clear...to just about

and no further. No sound...it just doesn't vibrate anymore because the aperture that setting necessitates bumps into the rim and is thus stopped. (You can clearly see this process on a cutoff rim with a mirror.) But...if I re-adjust a certain way (it's a jaw drop, mostly) everything opens up from that E right on down through the double pedals. The aperture gets "taller." More "O", less "oval." You can see that too w/a cutoff rim. On a bass m'pce or rim (1G-ish) I can take that same midrange set much lower because the aperture does not get stopped by the larger rim until much lower. Pedal G-ish for me. The classic Alan Raph/Paul Faulise Pedal G shift, which at least in my case is very similar to the low E shift I need to use on smaller tenor m'pces.
This goes for altissimo playing as well. There comes a range...around

for me, just above the classic Bolero/Dorsey high C#...where the midrange setting becomes much less efficient. And it's around

/b

...the Watrous"middle" note and the Ab from hell for so many players...where the possibility of a more efficient altissimo setting starts to cut in. More rolled in. That one extends well above

8va b

for me.
Just sayin'...when we say that we have "favorite" registers, what we are really saying is that our initial, most natural setting favors certain ranges. Once we understand where our natural middle is, then we can learn to expand in both directions much more easily. It's kinda like the footwork of a good martial artist or boxer. Really good ones have a basic stance from which all of their subsequent moves flow. A "balance." They then learn other "balances" in order to make their various moves. It can be a very broad and strong initial stance, an almost "on your toes" stance or any number of variations between those two extremes. You might say that a very broad and strong stance is similar to say the Phil Teele

b

starting note from which he travels in both directons. A sumo stance. A still powerful but more mobile stance...say Mike Tyson in his prime...is more like the

center of most beginner's books and almost all of Carmine Caruso's classic exercises. I hear it in most fine orchestral players. Somewhere around or above

b

? Doug Elliot starts a lot of students there, I believe...depending on their embouchure type. Me too. A good balance of everything. More like Sugar Ray Robinson. Boxer/puncher.

? Again...Watrous/Fontana, I believe. Light and quick. Mobile.
And so on.
Time to go practice.
Later...
