While beating Chris's scenario on hard for the first time gave me a serious sense of accomplishment, I honestly use Jill more than Chris. I like both characters equally but it really comes down to side characters and story for me. I prefer Barry over Rebecca and I like the Barry-blackmail angle.
@Hel Makes a good point about Chris's inventory, by the way. I realize that they have to give each character certain advantages and disadvantages but I think that giving male characters less inventory space is pretty cheap. There's really no reason for it.
I also feel that, with the remake, the tables kind of turned. As
@Hel also pointed out, Jill's lockpick isn't the jackpot anymore and Chris's lighter finds a more advantageous use what with the new feature of burning bodies to prevent crimson heads. I feel as though Jill and Chris are more evenly matched in this game with Jill's only real advantage being her inventory space, which can be made easier if you know the game well enough. It won't solve everything but it can cut down on backtracking.
