I'm genuinely convinced that I could handle most standard slasher films. So many victims in those films are people who either never pay attention to their surroundings or for some reason choose to ignore all the red flags. I would just leave as soon as I saw a guy in a mask standing around.
Halloween would be incredibly easy so long as you never put yourself in a situation where you're in a tight space with Michael Myers. As soon as something's weird, run or drive out of the neighborhood.
Admittedly, though, films in more secluded settings like Friday the 13th and Texas Chainsaw Massacre would probably be tougher. Like you said Texas Chainsaw would be pretty simple to beat just because you would realistically have extra gas to keep you going, but just for the sake of the plot, it would be difficult to get out of a place like that once your car won't start, and Leatherface definitely has the endurance to chase someone through those barren roads. Also, considering how connected a lot of the locals are with Leatherface and his family, getting help might be impossible.
But honestly, the biggest mistake most characters make is the mishandling of weapons. If you down the bad guy, don't toss your gun or axe or whatever just because you think you don't need it anymore. The bad guy always inexplicably gets back up.
Now monster films on the other hand are a way different story. I doubt I could ever stand a chance against a Xenomorph and the Thing is actually just unstoppable.
Oh, but I'd survive Predator just because there's no way the Predator would ever consider me a prey that's worth their time, lol.
