The two most famous portraits of Terry are Watts' "Choosing" and Sargent's "Lady Macbeth." They are probably the best, as well. The two others by Watts strike me as a bit too smudged.
I include some photographs of Terry at various ages for comparison.
Paintings by Watts were made around 1864 while they were living together.
Note Sargent's dedication to Terry at the lower right corner.
Atwood was a companion of Terry's daughter.
