We are still early. 
My hope is that SN and Coinos are getting their systems fine tuned (Coinos seems much improved lately) and ready for the growth that is possible- it's not guaranteed as we are up against massive and wealthy corporate algorithms but it is a possibility that this model of social media will eventually triumph because it has some superior qualities and Bitcoin use is central to enabling that.
I rarely bother with other social media now as the quality of content is so poor compared to SNs.

Is SN winning?

Honestly, as was mentioned already on this thread, I think the wallet thing is going to slow down growth. The first thing you have to do to start getting the whole SN experience takes a bit of effort. 

On top of that, one of the more popular wallets (CoinOS) has had a ton of issues, so really, you should be running your own node regardless. That's a whole other can of worms...
