I have several favorites for different reasons. I like several ICOs because of what they're doing, but I don't necessarily think that their coins will ever be in the top 50.
A couple I really like are Bethereum (social betting platform) and Synapse AI.
Bethereum is creating a platform for others to develop off of it and it allows others to white-label it to host bets amongst friends instead of against a bookie.
Synapse AI allows people to get rewarded for providing information that is then used for machine learning.
Thanks for the post and for asking!
