Each one of those guys you mentioned from Jack Reacher, Taken, Equalizer.... those guys had something called "TRAINING" and "EXPERIENCE." They didn't start out as nothing and then 30 minutes later wreck shit, suddenly becoming experts with no training whatsoever.
Ripley and Connor earned the prowess they were given in Aliens and T2 by suffering through the events of Alien and T1. By T2, Sarah was hardened, so seeing her in that tough badass role was perfectly acceptable. Same thing with Ripley.
Pretty sure using a lightsaber (and the force) has a much steeper learning curve than firing a pulse rifle or flame thrower.
Plus, the Marines' mission wasn't purely to "lets immediately go to the depths of the nest, get the girl, and then get out ASAP." Their mission was entirely different, so your comparison doesn't compute. Further, by that point, the aliens had been fighting for hours against the Marines, so they weren't all just sitting down there cozy, waiting for Ripley. Most were scattered all over the compound. Ripley had a nice direct route down and back, with minimal aliens to fight along the way.
So yeah. There's a difference between strong female characters that work, and near-infallible Mary Sues that don't. The only things you can point to that Rey wasn't good at was not getting captured. She got captured once, and would have gotten captured again at the end if it wasn't for Finn, but that's it. Otherwise, she goes from nothing, to better than where Luke was at the end of ESB, with no training, in 30 minutes....... that's ridiculous.
