Hey! Yeah, basically any beginner's method can only get you down to certain times (~30-40 seconds depending on how far you go with it) until you start to hit a wall. The main methods people are using these days are CFOP, Roux, and ZZ, with CFOP being the most popular. That doesn't mean it's best for you though; plenty of people use Roux and ZZ because they fit them better. Roux is best if you prefer more intuitive

methods (there still are algs to learn, just not so many), whereas ZZ is good if you really like algs and want to learn hundreds (the ~470 algs for full ZBLL aren't mandatory, but they are an option). CFOP is right in the middle, with 78 algs for full CFOP, and plenty of opportunities to work on intuition with F2L. I'd recommend checking them all out in more detail and deciding which one you like best from there.
