For manual trading?
Apart from the subjectivity (everybody likes different platforms), the platform one uses does not matter, any platform works well if you know what you are doing. After all, it's just an order placing vehicle with a charting ability.
Platforms vary, but I think MT4 and MT5 are the most popular ones. cTrader is relatively good too but personally I prefer MT4. At the end of the day they are all going to lead to the same things so mainly it is more something that has to do with the likeability and user interface I guess.
Interesting question! Both seem good to me. I use mt5 on fxview, and fxpro, altho fxpro has ctrader which I thought was nice, especially how the user interface is looking. But for some reason, I kept going back to mt5.
