Serious Question: Which will degrade the battery faster?

So, I just got my first 2025 model y couple weeks ago. I am wondering:

Which will degrade the battery faster?

A. Supercharging All The Time To 80%

B. Slow Level 1 Home Charging To 100% All The Time

I have not installed a level 2 charger at home yet, so I have been charging to 80% all this time. If slow charging to 100% will not significantly degrade the battery, I might as well just keep the charge limit to 100%.

Thanks for all your input.
