The question is subjective. We all have our own analysis of each of those coins therefore, we have different views and conclusions at one coin to another.
I'm also confused about being considered a game-changer.
What does it mean exactly? Game-changer to what? A possible price increase, like x100, x200, etc.? If not about the price, then what?
I have something "similar" in mind when I invest into something new. The idea of "game-changer" in my mind is the fact that it adds something that others do not have. Which means it could be 100x or it could go to zero but it has to be unique and add something better to what we already have.
We all know what we have in the crypto world, so when some place adds something new and better, we know that project and we are aware of it, not a different approach to same technology, not "a new way of using this awesome tech we had for 5 years" type of deal, I mean like literally something brand new in technology that they had to code into their blockchain. That's a good investment.
