Syscoin...meh.

Not bad, good, but not amazing.  Masternodes have built a stronger following for sure, but at this point in the crypto market, brand awareness and market penetration are essential.
There are so many platforms out there building great platforms, it isn't just about what is techinically superior.

And that's why I think, in the end, people still go back to eth.
It is probably the least viable from a technical standpoint, but it is by far the largest ecosystem out there.
There have been numerous times where competing companies have gone up with each other.
Even with better tech, there are many who have lost the battle cause they didn't have name brand awareness and adoption.

In the end, it is not about what is technically the best, but what other people consider to be the best.
And basically, all signs point towards eth.
