I was forced to use Python because it features binary decision diagrams,

I have to admit, I have no idea what you're talking about. I suspect,
though, that you would find a similar discussion of any other
programming language at least as nightmarish.
The one point that stroke me the most was the schism between Python 2 and 3. No
such thing with Mathematica: All its 11 or more versions are fully compatible,
I never experienced any problems in this regard.
The schism is not as wide as you are implying. Aside from "print"
becoming a function, which is blindingly obvious whenever you trip over
it, there is relatively little reason why an ordinary Pythonista would
care whether he or she was running Python 2 or Python 3. Python 3.5 vs
Python 3.7 is much more likely to be a relevant question, because of
course Python has evolved new features over time.
The statement "all its [...] versions are fully compatible" implies
Mathematica hasn't evolved over those versions. I sincerely doubt that
is true.
Another point is the bad online help provided to "teach yourself" Python. For instance,
it took me more than an hour to find out how to negate a Boolean variable, whereas in Mathematica
you would just type "Negation" in the Wolfram Documentation search window, and get the
information you need.
This is likely to be a personal thing. Mathematica ties you firmly to
its IDE; you get all the bells and whistles of that IDE, but only the
bells and whistles of that IDE. Python doesn't tie you to anything in
particular, so you have to provide your own bells and whistles (but can
provide any you can find or create).
That said, you are not making a good case for your research skills.
Googling "python boolean negation" got me the information in under a
minute, including the Firefox startup time. Reading through the Boolean
Expressions part of the online documentation at docs.python.com took
little longer, though admittedly that isn't meant for beginners. Even
firing up a Python interpreter and typing
>>> help("not")
didn't take that long (and honestly, "negation" is not the first word I
think of when inverting booleans).
I know one pays for Mathematica whereas Python is open source, but I've come to
realize now that this money is very well spent!
Question: Apart from a few commands not available in Mathematica, such as
expr2bdd, is there really any domain of computation where Mathematica is
inferior to Python?
Not knowing much about Mathematica, all I can say is "almost certainly."
