Now many ICOS campaigns are over and trust ICO Rating sites are really hard to determine as good and safe. Because i see a high-priced campaign to deceive the community. But there are low quality ICOS Rating sites but very good quality.
To me, that's just a very rare occurrence. An ICO that is underestimated by sites rated is usually scam ICOs, the sites judged on a specific basis to comment an ICO and I believe they are always right.
