POS is more user friendly I would say because you wouldn't need to go through all those mining rig setups. You just need to buy some pre specified amount of coins and stake it through a pool or an eligible wallet. So it makes the process easy for all! Also it doesn't need to use electricity so it is more environmental friendly as well.
PoS can be convenient but not better and not the best. PoW is the best in my opinion.
People are working in electricity companies, which means they are employed, the more electricity people use the more gain for the electricity companies and the more likely their works will increase. Bitcoin is not about the usage of electricity, bitcoin mining makes miners to let electricity companies to generate electricity which can lead to more electricity companies develop. But PoS is otherwise.
Also, how aboutining companies, PoW helps in the development of companies producing miners and other mining equipments, which PoSis also otherwise.
PoS is truly easy to setup but POW brings more development.
