I've seen the potential of VLB and Graft, their team really work hard to come up with a project that will surely help people. Their team were so active in providing information to a lot of people who wishes to invest in ICO but cannot decide which one to deal with. You can try visiting their white paper and Ann thread so you can see it  on your own, there are also feedback of many investors that will surely help you in deciding which one to take.
