You can see every rating in every ICO.
There are good site to see recommended ICO
Checking those sites you mentioned will only confuse him the more. I think what he actually wants is a mentor. Someone who has been into ICO investment for long to guide him.
I don't think we need a mentor, we can do it on our own using the reference he shared.
Besides investing in ICO now is not so profitable so if we will have to pay for mentor, we will lose more, honestly, I would prefer to buy now than to invest on ICO, I just feel the market of ICO now is not that good, we can invest again at the right timing, so let's wait for it.
