Look, if I were playing I'd probably do this. At the very least I'd be using Pathbuilder or similar as an aid to my manual character creation.
But I'm GMing for a bunch of people for whom this is their first ever RPG, and doing it by hand would have been a lot of extra work for me as I have to help them through the process step by step.
I've also discovered that Pathbuilder lets players share their characters with me, and it has an encounter tracker that automatically ties into their characters so I can easily keep track of initiative, or can roll Secret skills/actions for them. I can also verify what content they're using and that they haven't made any errors. Which is pretty damn handy!
