It depends on the kind of game I'm going to run. My current campaign is an epic narrative, so I had them roll, but may default to Standard Array. In a sandbox game, I would offer standard array or roll, but once rolled, ALL characters are kept. Rolling is generally better, but you take a risk when you do.
