Not the original maker of this image but it has helped me tremendously in learning new algorithms easily and bringing my time down. I used to solve it by cross, corner of cross, 2nd layer, 3rd layer cross, 3rd layer edge orientation, then finally the edges. Hope this helps new people learning the cube.
I would prefer j perm (R U R’ F’ R U R’ U’ R’ F R2 U’ R’ (U’)) for adjacent corner swap as it’s 1 move shorter and is faster for me
I learned it with T Perm, and have just started learning full PLL. I’ve found that a lot of the algs piggybag nicely off of T Perm, as I can think of them as slight variations of it. I don’t know if this works just as well if you learn 2 look with J Perm.
J perm is essentially just [R U R’ F’: T perm] ([A: B] means A B A’), so you can still derive T perm from J perm and a lot of other PLLs from T perm. And I think J perm can make predicting edges easier since the 2 edges that will be swapped are the 2 that you already see. I don’t use 2-look PLL but I use 2-look CMLL and I can easily predict EO (and EOLR if it’s a good case) after doing J perm.
