I usually see ICO's website icorating, icobanch, and icodrops. but do not fully believe in the rating list on the site, you should check first by checking the whitepaper.
I use these sites too when looking for good ICOs because the analysts are already experts in dissecting ICOs and I am just a newbie in the ICO field that's why reading about their ideas gives us an idea too on what to look for in a project. I also look at the community of the ICO and how the team responds to the questions of the members because through that way, you will know if they are knowledgeable with what they are doing and to monitor the progress of the project if they are following their roadmap.
In this forum, I look at the list too of some ICO enthusiast because they already have a rating or grading system to the ICOs so it would minimize our list as to what ICOs are ideal for investing or even joining the bounty campaigns.
