My favorite is ether, it has some success with creating dapps on its network but it still far from being the best. First of all the programming language it uses is really hard for someone to pickup. Not to mention how many good schools or even classes offer to teach high levels of solidity(ether coding language) at fair price. The only ones I have seen are imo trial and error class, where the professor is teaching for the first time a course where he/she hasn't work out all the kinks. Most people are to concern with price action to care what the project is truly trying to do. When I try to explain ether to my group of friends, I try to compare it to like windows, apple os or linux. You can have more than one OS in this world, each should be different from one another and catering to different groups of people/users.
