LOL I unboxed mine just after lunch when it arrived, but didn't actually get around to turning it on until around 8pm tonight.
First time I've tried the "transfer from another phone" for real where you scan the circle of blue swirling dots and it transfers everything. Usually I manually log in long enough to update iOS if it needs it then reset it and restore a secure local backup from my PC. It definitely seems like the direct phone to phone bluetooth transfer is the same thing as I only had to log into a few things just like a secure backup restore. Seems like my days of dealing with secure backup restores are over.
Well, actually technically my iPad Air back in January was my first use of that direct transfer, but I have far less "critical" apps on that. For example my phone is the device that I run Microsoft Authenticator on with a whole bunch of other non MS accounts added. I was a little worried about breaking that and having to go dig out restore codes for a number of accounts to fix them all.
