IEO simply better because there is a guaranteer. And it comes with a guaranteed listing on an exchange.
But you are buying the same token. So if the project is shit, IEO won't be enough. You will end up losing money.
Can't agree more. The really thing that IEO does is that it guarantees listing. That's actually all. Everything else depends on the project. But of course even listing guarantee is a big big step ahead compared to 2017 and 2018 when many coins did ICO and then never listed on any exchange or on decent exchange.
