KickICO were popular while dawn of ICO, now as I see they aren't so popular, but they have their clients which help them to function. I think when people remember about ICO again KickICO will be on the top.
When I found KickICO I have lots of doubts because I thought its a scam, but after a couple of years I understood that they are really active and developing project which will grow
Not sure about their tokens but Kick ICO can prove their transparency. So I understand your doubts
