It seems rather obvious for me:
saving: useless, you just store value waiting for... I don't know nothing probably, just in case
Investing: making the money move and getting more money in the end.
Of course don't invest blindly, but invest.
Investment involves risks, and very few of us can afford to take that risk, majority of the people would go for savings as they don't want to loose their money, savings can take care at the time of emergencies but the money you hold is limited.
In the end you'll have to decide what to do with those savings.
If you spend them well it's no longer savings, just delayed spendings.
If you gonna use them hoping for a return on investment then it's investment.
