Kraken has a ETH2.s to ETH trading pair to trade staked ETH to unstacked ETH. Should I just buy some staked ETH there and get a discount instead of clicking “stake”?

I am considering staking on Kraken.
They have a big "Stake" button and when you click that your ETH becomes staked ETH.

They also have an trading pair made off ETH and staked ETH and as far as I understand this is a way to escape the lock in until ETH2.0 if you want. The drawback is that the staked ETH trades a little under 1 ETH.

If I understand correctly that means I could get staked ETH for a slightly lower price. Should I just buy that instead of using the big "Stake" button?

Am I missing something here?
