Without constraints I would obviously choose MyHDL as the first option,
if only to get the bugs out of my own stuff :-)

However, note that even then I will likely need VHDL in the process:
as the result from MyHDL, to integrate with 3rd party stuff, to
synthesize from. From now on, I would always use Sigasi HDT to
support that work. Note also that I could use refactoring e.g. to
create hierarchy out of a flat design from the MyHDL convertor.

MyHDL and VHDL should not be viewed as opponents. MyHDL's main
inspiration is obviously VHDL. MyHDL can be viewed as VHDL's
"scripting companion". I have a lot to thank to VHDL, but I've
written so much of it already that it's also a simple matter
of not getting bored! It's true however that Sigasi HDT makes
it much more fun again. It avoids most of the boring stuff.

I don't think my own situation is that relevant however. I believe
that MyHDL (or at least its concepts) has a good future in the
longer term, but there's also the short and medium term to take
care of. There you have all kind of constraints, personal
preferences, company policies etc. Realistically people in
different situations need different solutions, and for me
it's not a contradiction to work on various fronts of progress.
