Good and simple point. I think the lists are good to follow. Those are really some of the best coins around to invest in both long term and short term respectively. However, I would also like to add LTC, sumokoin and Dash on the short term and Waves in the long term. Just to give some more options you can choose to invest in. I think those coins to name a few are the most reliable and the surest you can get good profit from. However, like any venture in the cryptocurrency market, there is no 100% sure way to gain profit because there are so many trends and movements that can affect the market.
