Most used alg?

I'm currently learning full OLL slowly and also some PLL, but I'm picking and choosing the algs I'm learning. I recently saw the linked video for a fast U perm and it made my solves so much faster because I seem to use it in A LOT of solves.

So I thought I'd share it, and also ask what your most used algs are? Post links if possible, let's all get faster together.
