well from my point of view its in the same league as eth and zcash, you can see from the price alone,
eth and dash have important updates incomming and only future will tell which will emerge as the winner.
i wouldnt be surpriced if eth wants masternodes or something simliar (like mastersmartcontacts) sooner or later too.
sadly i ignored dash while getting into eth early, here is a nice interview with ryan taylor ceo of dash https://www.youtube.com/watch?time_continue=1&v=t4dI-dXhEfo
