Enjin has a good dev team, is doing a very good marketing campaign, and will create a very good feature for games. I'm a gamer myself, and I would love to be able to bring those special itens across games, or sell them for profit. We all know how important itens in a game are incredibly valuable for players, so they might have a great market there.
Filecoin fights the monopoly of centralized storage, so it looks like a good project as well.
As for ARToken by Cappasity, they also seem to have a good team behind the project, that already worked in big companies, so they probably know what they are doing. I haven't seen any marketing in the forum, but I see them around, so I think they are getting to users. Their project is very specific, but it has great potencial, because it 3D content and VR has a great market in the world and it generates millions of dollars.
Finally Unify has a very simple and achievable project, and quite important for the crypto world in general. They can't go wrong if they aim to help people get engaged in crypto. They will he helping themselves and all the crypto in general. Also they have very clear goals when it comes to get listed in exchanges, which is also great for the coin. Their "small" goals are quite achievable and the long terms ones, like the crowdfunding platform have great potencial, so I think it will be a good investment.
Agree about ARToken and definitely Filecoin. Will take a look at others too
