A5E would've taken longer. In retrospect I could've short cut some steps to make it more timely. Like for example, I could've gone through making the character with them? There were some additional factors influencing what I decided to do w/o going into too much detail. One was this was the first time they had come over to visit, so I preferred someone their age who'd be playing at the table with them to help.
I only offered an occasional comment once in a while.
They also were I would say, were hands on. They hadn't looked at a PHB at all. When picking whether to play an elf, dwarf, halfling, human etc, they had a preference of what they might want to play, but wanted to read through all the descriptions of the other races in the book, even after their friend gave a brief description of each. On certain steps in character creation where it says "roll the dice," they preferred to read all the options and pick what ones fit the idea in their head best. Which I let them do.
Mostly my thought in bringing this experience up was that a new edition would benefit from taking some of the editorial/layout choices other 5e adjacent games have used, to present game information in a way that's more accessible and easy to find.
