Paid presets are one of the biggest scams available for purchase to us musicians in the modern era.
Okay, now that I've got you upset, angry, or otherwise riled up and emotionally invested in my post due to my unrestrained hyperbole, here's what I mean: Of course they're not actually a "scam," but in a way they are - only, the one fooling you is yourself, thinking you can cut out the time and expertise required for a tone that you are personally satisfied with, electrified by, and emotionally connected with.
As others have mentioned, you can learn a lot from the way someone builds a preset, so paid presets aren't a complete waste. But unless they built it using your ears, your fingers, your guitar, and your playback system, it's not going to sound the same and, were they in your shoes and heard & felt what you're hearing and feeling, they likely would have tweaked things differently.
The long of the short of it is that you just need to learn to make your own presets. Don't expect perfection right off the bat; scroll through the factory presets (Fractal being the ONLY company who has actually useful presets) and find something that gets close and hone it from there.
