The most important thing DASH can is sending in less then 2 sec with a small fee. Bitcoin tries to have with lightning network but it has to be working direct with BTC adresses in wallet, otherwise it will not work.
I like Monero earlier, but the only thing it can better then DASH is ASIC resistance.
Its too slow even with a 2 min block time.
And when you have Miningrigrental or Nicehash website its equal if a coin is ASIC resistence or not. Only solution there is POS (o maybe something complete new), but it will take time until people understand that and will get it in Top 20
When v0.13 is fully activated on the network (within a few weeks), Dash will have automatic Instantsend on default for small transactions (4 inputs or less), which will be about 90% of Dash transactions. This will be without any additional fee.
In short, once actived 90% of Dash transactions (small transactions) will be sent and received within a few seconds on the network, immediately protected against doublespending and without any additional fees (just the normal low transaction fees).
This will strengthen Dash use case as being used by anyone as digital cash and specially in Venezuela this will prove very helpfull as small transactions are taking place a lot there.
Personally i rather have the network security that Dash ASIC miners provide, combined with Dash Chainlocks that provides protection against 51% attacks (
https://blog.dash.org/mitigating-51-attacks-with-llmq-based-chainlocks-7266aa648ec9),
then having to hard fork a network every few months to block new ASIC miners on the network and thereby actually increase the risk on 51% attacks on that network (specially in a bearmarket where prices are low and its easy to just rent the hashpower).
Not only do consecutive hard forks scare off investors, they also encourage bad behaviour under miners (which is why Monero after having hard forked to ban ASIC miners before, is in the exact same situation now again).
This is a chart of the miningpools that are currently mining on the Dash network (GPU and ASIC miners) :

You can have ASIC miners and still have a nice spreadout of hashpower over different mining pools, you just need to encourage good behaviour.
