Dash is not even private. It was just a marketing plot.

And in that case you are better off with LTC or BCH.

On a technical level Dash doesn't offer privacy on any level that Monero does. And if you don't really know much about the tech, just look at what currency is being used on Darknets where these things are critical. I don't think any accept Dash (at least no major ones I know of). It's Monero and Bitcoin with Bitcoin only still there because it was "grandfathered in", and has the most liquidity, and slowly being replaced by Monero everywhere.
