I use a Milwaukee M12 Hackzall with a short wood blade as my go to drywall cutter.
Makes quick work of it, not as dusty as a spinning blade.
The only problem I have encountered is you have to be diligent with blowing the dust out of the tool when you are done. I have killed one by letting it get too plugged.
I am a trained professional..... Do not attempt this stunt at home.
