PPPU variation is better but with a pause at the top so you get the lean.
Leans are much better once you can actually lean decently far because static positions only confer some benefits with about 30 degrees of the angle you're leaning with less as you get a bit further away.
Put feet at approximately shoulder height when you are doing this, and SQUEEZE the heck out of your abs to keep your back from arching.
Best to stick with compounds for now + static planche work.
Planche leans can be coupled fairly well with the planche progression pushups.
