The CFOP method is the most widely used speedcubing method. It is a more efficient version of the Layer-By-Layer beginner's method. It is very popular due to the vast amount of resources that teach and improve upon the CFOP method. Many advanced speedcubers such as two-time Former World Champion Feliks Zemdegs and former world record holder and champinon Max Park have also learned additional sets of algorithms for the last slot and layer, such as Corners of Last Layer (COLL), which orients and permutes the corners when the edges are oriented, or Winter Variation (WV), which finishes OLL while inserting the last pair and ZBLL, which combines the solving process of OLL and PLL in only 1 Algorithm.
