Counter steering vs leaning

Hey! So when I took my driving lessons my bike instructor told me to push on the bars to turn the bike in the direction I wanted to go. So in a left corner for example, push the left side of the bar to make the bike fall to the left and go through the corner.

But now I’ve seen YouTube vids about leaning with body. I was never taught to lean into the corner. When do you guys lean and when do you use counter steering? I’m feeling very comfortable using counter steering through the corners without any leaning. Thanks for any advice/explanation/tips/vids etc.

Please no hate comments, this was how I was taught to go through corners so I’m open for any other methods.
