It should not really matter, I recently was asked to deliver a design in Photoshop for a large company, it took me 20% more time than it would in more modern tool, but this cost was lower to them than changing their handover process.
I think most designers with a bit of experience is able to work in any design tool easily. When given the choice I do still prefer Sketch, with the right plugins it feels really more like a power user tool to me than any other tools out there right now.
