Outside of Dungeon Crawl Classics, anyway.
The feeling of seeing someone with a full deck of 0-level characters just do the bonkers, foolhardy thing with one of them is a glorious one, whether I'm a fellow player or a Judge.
Now, as for my own characters, while stats aren't the end-all, be-all for my personality, I definitely adjust based on the framework that the stats give me. That high charisma, low wisdom dwarven bard will be more blustery, more self-aggrandizing, a little more oblivious. Personality traits I might not have selected but for the numbers of the stats.
