I tried the wallet and didn't like it + the technology is very much in it's early stages: The vision is not to rely on a central coordinator for it to scale so your really betting if that will be overcome.
Personally I prefer Nem as these guys don't need to hype and are focussed on developing kick ass features that no one else is doing making it far more interesting to me in terms of utility.
Yes IOTA is definitely still in its early stages. But one got to admit that in case they can overcome their current issues the project might actually become one of the Top 3!
