Here's my list to find the best icos in the world.
icodrop,com
polkastarter
Those sites are the best sites to get the upcoming ico. I have been using both since last year. Those sites were also giving very huge ROI dude. You can try to use it.
I agree in terms of good source icodrops is the best ico rating. Polkastarter is also nice however it's quite hard to be included on their projects. Aside from being limited, it's also requires you to hold their utility token to be able to join. I agree that ROI is the best on these platform. But unfortunately I never able have a chance to join on this IDO platform. Icodrops shows that they are really capable of providing legit new projects.
