I don't get why people based on websites that they don't even know who are the people who give these ratings. Those 'so-called experts' also don't have a lot of strong proof that they are best on what they do. Anyone can also give rating based on their opinion because that is how those rating sites does their thing.
Of course these are only opinions but they explain how they came to their opinion. You can factor them into your decision making but should not follow them blindly. The best advisor is still your own experience.
Example: I see you are promoting Gigtricks, I was also initially interested. On ICO Bench they get a very high overal rating. Then I read on a review from an expert who wondered why they need 35 million to build a platform for freelancers. Then my warning lamps went on...I had invested before in projects with a high hardcap and they collected far too much money. The problem is that the token is then overvalued from the start. So I stayed away. Not because of following ones opinion but to combine external indictions with my own personal experience. Not saying it will fail, but I passed on it.
