Oh boy, here we go again.
As in every other thread, there are a ton of factors that contribute to tone. You take Marcus Miller and give him Flea's favorite brand of strings do you think he's going to suddenly sound like anyone but Marcus Miller? Of course not!
High end instruments are expensive because they play better and feel more comfortable, and also often have features that are not available on off-the-shelf models. Tone is subjective, and most of us who play high-end instruments will of course argue that our boutique axes sound better than something off the shelf at guitar center, but it's relative so there's no way to prove who is "right."
You sound best when you're comfortable. Playing "better" strings that don't feel good under your hands is not going to improve your sound no matter how many YouTube videos tell you they're the bees knees.
