Its true, because IEO offer a safeness way of invest, crowd fund on IEO is handling by third party (exchanger partner), so its less possible to being cheat on IEO.
I would say that comparison between IEO and ICO is like comparing Apple smart phone and NOKIA smart phone. This example suggests that though ICO might not be dead and might still be gaining some funds somewhere but IEO has been able to fully cover the market and if not fully, it has captured more than 90% of the market so obviously it is IEO that is leading.
