I use its lexical-analysis functions a lot, for many different 
purposes. It works quite well enough for me. However, I can 
generally myself design the language to be analysed. I would not be 
surprised to find some awkward problems with languages that have 
been defined by others -- but that probably holds for any general 
lexical-scanner tool.

I very much like the absence of any "generator" step -- a simple 
"gnatmake" is enough to update the application after a change to 
the token structure.

I have not used the parsing functions in OpenToken; they did not 
exist when I started to use OpenToken, so I got into the habit of 
writing my parsers manually.
