This is both true and not true. The basic filter circiut will have
the same sound. What makes it sound different is the response time of
the vactrol. A vactrol is basically an LDR and an LED facing each
other and encapsulated in black plastic. Since they are put together
in a non precise manner, not every vactrol will behave the same. So
the response times will vary, hence the difference from one filter to
the next. The difference will be marginal and not widely different.

Here is a url with some samples of a vactrol filter and a vactrol
phase shifter.
