Oh, I had not. It looks better with collapsing=1, indeed. A few neq
questions comes to me:
Does ConTeXt not use the same prime character as in TeX/LaTeX? Or has
something changed in latin modern? See the attached pdf files
(derivatives.pdf from ConTeXt and primetime-crop.pdf from lualatex). The
prime character looks more slanted in ConTeXt. It also almost looks like it
is cut horizontally at the bottom of the character. Also, the space between
the two x in the subscript looks a bit large to me. Is that easily tuned?

The ConTeXt file:
\starttext
\startTEXpage[offset=1bp]
\setupmathematics[collapsing=1]
$f_{xx}''$
\stopTEXpage
\stoptext
The LaTeX file:
\documentclass{article}
\usepackage{lmodern}
\pagestyle{empty}
\begin{document}
$f_{xx}''$
\end{document}
