Depends on the game
Some games have a tendency to make their hardest mode absolutely insane, so Ill go with the second hardest
Some games are just easy no matter what you do, so I pick the hardest mode and impose arbitrary restrictions on myself (ie. no using x weapon/skill because it's overpowered)
of course, this is usually just something I have to guess at based on the genre and developer.
