I use MT4 it is very much easy for me. Beginners can use MT4. Once I install MT5 but I can not understand this. It is very much difficult for me. I think that MT4 is easier then MT5. Only use F9 I can buy and sell for trade in MT4. We can set chart using Toolbar. MT4 is easy to see history of trading and current trading using History and trade button. I think all beginner should use MT4 to operate easily.
