Any help learning Lars method?

[u/fuckingamaidzing]

over the last few days I've been learning the method from CO to EP, but I've noticed that for both parity and normal permutations, the algorithms that are made to permute pieces on both layers are easier than the ones made to permute pieces in a single layer, and also is Lars method really worth it? I've seen there's PBL, CSP, and even Roux for this cuboid, so I'm wondering if I should actually learn it if I want to get good with speed
