Some of the ICO rating sites are good to filter them, then do more research on any with decent ratings.
I currently use ICObench to filter good ICOs from the not so good ones. Soon, I'll be moving to a much better platform where it actually allows us to buy from within the platform itself. Anyone heard of Menlo One? It doesn't seem like people have taken much notice of this project probably because they're busy promoting their own coins. I honestly think this is one opportunity I wouldn't want to miss.
This is a link to Korean Jew's interview with Menlo's CEO where they discuss the project in detail
