Well, for the previous reply, I just looked at the difference between
LaTeX and ConTeXt's definitions.

I checked up with the TeXbook and both should be equivalent. Quoting
from the TeXbook
* double bend at the end of page 144
If you say \nolimits\limits (presumably because some macro like
\int specifies \nolimits, but you do want them), the last word takes
precedence. There’s also a command \displaylimits that can be
used to restore TEX's normal conventions; i.e., the limits will be
displayed only in styles D and D'.
* page 292 (summary of math mode)
\displaylimits, \limits, \nolimits. These commands are allowed only if
the current list ends with an Op atom. They modify a special field in
that Op atom, specifying what conventions should be used with respect
to limits. The normal value of that field is \displaylimits.
So, if I understand correctly, there is no difference between
\mathop{...} and \mathop{...}\displaylimits.
