There are sites that will make you see ICO's ratings this rating was researched by teams on that particular sites you can see expert ratings and what do they think, about given names of the token but if you are having doubts on their work you can sure research and see for yourself, I really think that there is no 100% ICO that will be compatible with you there will always be a flaw, And we can not know any good ICO until it shows its true colors so we are technically sitting ducks waiting for an ICO to makes its move whether it can be a success or not, It will be on the developer's hands if they can make it happen, So I can say that there are no guaranteed ICO's and not all are pertaining only to scam but to ICO that are not successful with their hard cap or soft cap this will lead to stopping the ICO itself.
