I usually don't judge currencies by what investors or marketers have done with them, although all the hype and the pump and dump/fake news was pretty bad. I didn't know much about IOTA back then, but after I started to actually understand the purpose of using a DAG approach rather than a linear blockchain, I still think it's kind of revolutionary, although I have no idea how well it's implemented in IOTA or whether it was even the first currency to introduce this.
