The different between staking and mining is pretty simple and it is the cost. The cost of mining is a lot because you need to buy a lot of expensive equipment and you also need to maintain and pay for more expensive electricity bill every month and after those expenses that is only the time you will get your net profit while staking is just simply buying a cryptocurrency that is POS and then keeping it on the wallet that support its staking and that is how you are going to get reward or profit.

In my opinion, staking is more practical because it will cost you less compare to mining and staking is not hard to maintain because you just need to make sure that your wallet is up to date to make sure that you will not miss any rewards.
