With the definitions provided by the OP, just ask for your own opinion on each of them.
I am more convinced in the layer 2 network compared the layer 3 or layer 1 because as of the moment, that's the hype now and popular.
Taking a new projects as your investment is a big risk and it can bring investors down, because it takes a long time before you can see a new project doing massively well to give opportunity to their investors to experience good income from their investment. I have never seen all those three projects from the market before, show that they are new projects, because I'm use to many projects in the market but those ones are new in the market, and I have noticed good performance from the old projects because their team are doing well all the time to keep the project to continue increasing their investors income to make others investors to know that they are capable to make the project continue displaying good results. If the OP can use small capital to try those altcoins will be good, so that he will know how to increase the capital in the future base on what he will going to achieve from those altcoins investment and it will make him to determine whether he will continue the investment or not, because some investors increase their capital base the good result they have achieve.
