Yes, Golden Hornet has improved some for me with age. Mine was always clean enough, but the fruit would dry up and not fall until the next spring. I still have at least 60% of the fruit that dries up and doesn't fall, but enough drops to be meaningful. It's possible that it might get better in 5 more years - we will see.
I decided to give the sheepnose one more year. It is not growing very clean, and it has zero apples on it. In fact, it has never produced a single apple for me in all of these years. Rather than topwork it, I'm just going to cut it down, because I can tell it is on a B118 rootstock. I have it braced with 2 T-post, but another B118 standing 60 yards from it was braced the same way and got took down in a storm this spring. It just took the T-posts down with it.
Near that Sheepnose is a Grey Ghost that was planted at the same time. It does have apples for the first time this year, and they look good. This tree is not on B118, because it is anchored very solid. I've seen quite a bit of fireblight on this tree in recent years, but it seems to be building a little resistance to it as the tree ages. That happens with some cultivars, but not with others. I'm watching this tree closely this year to see when those apples fall. This could be a tree that I am eventually happy with - we will see.
Move down another 30 yards and I have a Droptine that is also solidly anchored in the ground. It has been producing loads of fruit for years, but they just dry up into mummies that are useless. It will topwork this tree to something else next year.
