The ICO isn't the most important concern but is a real one that one should consider when investing in NxT and its future potential. Additionally , while Nxt does have much better development than many alts , it is pathetic compared to all the development from a software and hardware side in the Bitcoin ecosystem. Don't drink the marketing koolaid and compare the NxT wallet to Bitcoin QT. Bitcoin is much bigger than that with many projects and many hardware and software implementations..
