They all have same functionality in the end. But if you ask me your video doesnt look very bad. Slowmo behaves sometimes very awkwardly. The node is changing the Root orientation and since the speed is not changing i would expect some foot sliding. That slowmotion probably makes it look like 3 times worse than it is actually. A Lerp with an Alpha somewhere between 0.04 and 0.05 should be good. I assume Strider has a regular Lerp Alpha for Smoothing, which is between 0 and 1.
