You should not find the best but the ones that are very profitable. Because even if they are not the best and just an average but they are cheap and have low supply, you will still make the best profit multipliers and that's what important for investors.
There are different types of investors, there are some that are chasing for profits but there are some that are looking for the technology and sense of that ICO. But we are all there of looking for those ICO's that will certainly profitable for your money. And for combining the two types, you can try it out with VLB. I'm not promising anything but if a project that will be used in the future in the car industry it will make its demand and value higher when people start using it.
Ive heard vlb before and i actually joined their campaigns. their project is quite promising after i read some of their visions and misions from their website. Overall vlb is indeed one of the few legit ico that i can recomend if your looking for some profit and usefull service at the same time. in my case im not a fan of ico because im not an investor at the first place rather i only joined them in order to earn some rewards.
