That really depends on what you consider "competition", there will certainly be several networks that will have a role in the future of crypto. I don't know enough about the projects you mention to have an opinion on them but I think Dash success at this point depends primarily on Dash and maybe tangentially (for now at least) on the state of Bitcoin and the crypto industry in general.

I think Dash full node incentive program is a killer feature, it promotes participation and gives people a sense of ownership of the project. The incentives are better aligned and provides a way to generate income on investor holdings which in most networks remain idle.  The governance system and funding model in Dash also creates strong network effects and allows the project to pivot depending on changing market conditions, so Dash is dynamic and can adapt to a changing environment giving it greater chances of long term survival.

Dash's longer term plan is to create useful tools for end users and to foster an ecosystem of merchants and service providers, it has a plan, a team and a funding model to achieve that goal. There are still of course risks inherent to any business venture and we will see how the market evolves, but compared to what is out there at the moment I think Dash has a strong case to be one of the projects that survive long term.




Edit: I just wanted to add that Dash accomplishes this while still using Proof of Work to secure the blockchain (avoiding PoS) which is an important plus in my opinion. And only uses stake holdings for governance purposes but only attached to full node operation which I think is a superior way of doing it than just voting based on coin holdings without a direct network responsibility like masternodes.
