I was researching independent reviews of ICO's and I came across a few websites recommended by people who have been looking at ICO's for a while.
They also have a SCI (Smith and Crown Index of leading crypto's)
It might be a bit early yet but looks promisinghttps://www.smithandcrown.com/icos/
http://icorating.com/
A more definitive list but I've not got around to look more closely.
