I must admit MantisWeb has me intrigued - I am looking forward to more details. Might be too soon to call it, but this coin does seem to be breaking from the trend of new coins pushing nothing but "anon" as their selling point.
TOR etc will be included in the Mantis 2.0 UI update on the roadmap, but we do not see it as a selling point as every coin has it these days. We would just like to have TOR etc available to all users as an optional choice.
More information will be posted soon about MantisWeb, awaiting other devs to come online!
