IPad Pro 2021 512Gb vs 1TB?

I would like to buy an iPad Pro 2021 soon. I'm currently fluctuating between the version with the 512Gb and the one with 1TB. I want to use it as a laptop alternative so I don't own one.
The 512GB Ipad has 8GB of RAM, the other 16GB of RAM.

Is this difference very noticeable?
Which one would you choose?

So if you really want to use it as a laptop alternative, I would take it with 16GB RAM, as this is also suitable for apps that use a lot of power. In general, I would play it safe and take the 16GB RAM and 1TB storage, you can't go wrong with that.
