For cubers like me (30 s. Ao5), this solve of Shawn Boucké from SpeedCubeReview channel is a brilliant demonstration of how efficiency is important and as speed should not be confused with haste.

Don’t stress about trying to become sub-30 on the Rubik’s cube. Just be efficient and Turn slowly

Another insane video of him:

The Slowest 8 Second Solve Ever

I discovered Shawn Boucké few days ago in his Roux method tutorial and he is a very good pedagogue.
Also, he has a very nice turning style.
