I think project is a lot more important than how it is done. If you find a good project and it is run by someone very known in the world of crypto or even someone that is just a good business person and have a staff of great developers and marketers and designers etc etc then that project could be ICO or STO or IEO and it will still be good regardless of how they do the offering.

However, if there is a coin that is offering in any way or shape and sucks, the owners are idiots, the staff are very small in numbers and not great then it doesn't matter what type of offering it is. So in the long term a coin has only one offering option yet it will continue to exist years after that stage which means the offering is really unimportant in the grand scheme of things.
