I've been doing small SIA trades for weeks now, and doing well. I often ponder the SIA/Storj question myself, but I'm with SIA, just my personal choice. People's mileage and preferences may vary, but I'm counting money I made on SIA trades, so it works for me.
That's true, SIA has the capability of troubleshooting other servers in a fast manner.
Allegedly, they already have a significant eco-system of data centers and providers in their cloud. I dunno. I make money day trading their coins. And I do good with sia that way.
