In my opinion, Jill would be the better to play as. She gets a lock-pick, skips some parts in the game (like the plant boss battle where she dosen't need a chemical, but she dose need Barry with flamethrower), dosen't need a broken shotgun to get a working shotgun, gets a grenade laucncher, can get infinite ammo with the grenade launcher, she can get Barry's Magnum that kills Tyrant in 1 hit, gets more slots, dosen't require you to leave the piano room to get in the passage, and you get her RE3 outfit as well as looking like Sarah Conor.
