Don't think about the sources too much man, you already got great sources at your list. Which are good for getting info for new ICOs. My advice though is that don't rely so much on the basic infos you get on those sites about ICOs. Knowing the name of a new ICO is good enough info to absorb from these sites.
The rest? Research about it. Specially the developing team of the ICO tonsave time. And if the team is good or great, then proceed on reqding the amm thread of the ICO and them the white paper next. Doing these can guve you a lot of chance to get into more promising ICOs than scam ICOs.
Good luck.
That goes without saying that making your own research is a must. But the author of the question is a newbie so that might be wise enough to try to find some experts' opinions like on icorating.com to start from there.
It's hard to draw the right conclusions solely based on your own analysis when you do not know how to analyze (yet). So checking out resources like icorating, smith and crown, icobench, something else like that could be not a bad idea in this case, but of course, you should always critically treat someone else's advice in any situation because it's your decision and your money in the end.
