I voted "I used a fixed array, either the one in the book or a custom version of it." but there's more to it.
This isn't technically one of my characters, but my players in the game I run. I wanted the characters to be extra strong for the setting, to set them even further apart from other adventuring groups, and so I wanted them to have higher stats than normal. At the same time, I personally dislike rolling for stats and enjoy static arrays, but I know my players prefer to roll for stats.
I asked everyone to roll normally, using 4d6 drop lowest, then record the array they got and send it on our group chat.
When everyone posted their arrays, they got to vote to see which stat array they liked the most, and they got to use that array for their characters (voting for multiple arrays allowed).
They actually voted for two arrays, so they got to choose between them. Both of these got five votes:
17 | 17 | 12 | 12 | 11 | 10
15 | 14 | 14 | 13 | 12 | 12
A couple of them ended up going with the more balanced one, and the ones that love to power game went with the double 17s one. We're 40 sessions in and everyone's been very satisfied with this, there's been no complaints, they all still got to roll dice like they wanted and it seemed like everyone had fun during the whole process, like a mini party game before character creation, and I'm content as a DM that everyone is around the same power level stat-wise. It's also allowed to throw harder stuff at them, which was part of my goal.
