To be complete :
You stake your stacks.
Sometimes ppl use piles and not stack, but I prefer stacks since a pile suggest a BIG stack.
Then there are ppl who prefer steaks rather then stakes but they are very likely not into POS coins or crypto all together.
So to steak or not to stake a stack would not be the question for them.
While for some of us to steak or stake a stack would be a difficult question to answer, especially if you have a good apatite for both, whether steak or a stake.
