I do all my writing using Scrivener. Long since stopped using simplistic word processors such as Microsoft Word, which went long ago as I do not participate in the Microsoft hegemony, OpenOffice.org, LibreOffice, or Apple Pages. Although keep the last two around for the rare cases of having to deal with documents in formats that Scrivener cannot handle.
About the only pieces of writing that I do not use it for are short responses like this. But again when a reply addresses complex issues or multiple comments I compose them in Scrivener to make a cogent and coherent argument. As this has lengthened it too might need to continue being drafted in Scrivener.
As to handwriting I have commented elsewhere here that using a stylus on paper is impractial for me. The friction of the marking medium on the surface slows me down and in consequence fires my dyslexia which in turn causes me to leave out unimportant words such as not. Being able to touch type and look at the screen not my fingers results in better lexical capture. (And I have used the onscreen keyboard on my iPad to touch type too.) Althougth the proximity of fingers to the screen on both my laptop and iPad will occasionally result intrusion of my second language which has no tense system and therefore verbs go unconjugated.
No way would I contemplate or consider ever transcribing material ā my own or anyone else for the matter. The recent inclusion of reasonable OCR capabilities within iOS/iPadOS/macOS for grabbing text from graphics is a boon to quoting academic sources. (Yes, I use Scrivner for academic purposes too.)
I am something of a heretic with Scrivener though as I have never subscribed to the index card metaphor so no Outliner or Corkboard! The Binder is sufficient for me through the use of short snappy titles for the documents there. Restructing parts of my manuscript is a simple drag-and-drop within the Binder. When I am unsure of the exact nature of restructing required I use Collections within the Binder window to play with alternative narrative orders.
