What is your purpose to be exact? Those coins would be useless unless you have a knowledge in background of financial literacy, risk management, blockchain technology, etc. There are many factors to consider before holding a coin nor investing in one, but if you would just asking "what to use", then it would depend. If you want a long term investment, then TRX, XRP, and LTC is good (while their price is low). If you want a short term trading, anything can be good as long as you are a good trader. But if you would wanna ask what system is good, then XRP is nice with its low fees and fast trasnsactions.
