Is there any downside to using 2 sheets of 9.5mm on studwork walls (will
be skimmed) vs 1 sheet of 12.5mm?

Not really... mostly advantages. Costs a bit more, and some cavity wall
fixings may have a harder job, but there are plenty that will still work.

I have relatively little wall to cover compared to ceilings and it would
simplify ordering and storing to work with one type.

And I could overlap all joints in the 1st sheet which seems like a bonus.

Its standard practice for shop fitters I understand (although they tend
to do 2 x 12mm). Give a more rigid wall and better sound isolation.

Just wondered if there were any major downsides?
