I am a hobby groomer! People joke with me all the time! But my horse is out 24/7 and likes to roll.
I don’t know any of those brushes. I really like a stiffer brush (not amazingly stiff) and a soft face brush (not amazingly soft, it has to wipe hairs off. Both are cheaper brushes. I got the stiff brush from Dover (the brush part isn’t all plastic, I think) but it is somewhat stiff). The soft brush is a super cheap plastic brush I inherited 20 years ago and the ends are so frayed that it is really soft yet retains its shape.
Besides those two brushes, I use these super cheap items:
Epona shed flower

NOTHING strips of caked on mud as well as this. No brush works as well.
My friend gave me a plastic curry comb last year and NOTHING I’ve used helps shedding horses as much as this without damaging hair (well, yes a product does but is no longer available - it is my favorite dog rubber hand curry):

I use something like this to get the hairs off the face before the soft brush:

While this seems like a lot of items to use, the epona curry hands down is the best way to remove caked mud rather than a brush. I regularly wear the teeth off of them. The $2 plastic curry removes hair and mud from the legs better than any brush. These two items cost together under $10 and saves me SOOOOO much time. The plastic curry (third link) also saves me time because my horse loves to roll and this gets caked mud off of his face quicker than any softer brush I’d use on his face.
If I had to (and I have), I can quickly clean the areas where the tack go with the above items and brushes and tack up in a hurry without my horse getting uncomfortable. You can apply as much elbow grease as required for winter or summer coats.
I’m sorry that I can’t add much to your original post, but I wanted to add some stuff that might save you time when grooming your horse.
