XDN vs FCN?

[generalheed]

I've been doing quite a bit of merged mining lately on MinerGate (yes I've heard all the stories), and their smart mining option in their mining software automatically mines XMR+FCN (FantomCoin) for me. There's an option to switch to XDN (DigitalNote) instead though. Looking at the exchange rates as well as the speed at which I can mine each coin, I found that doing merged mining with XMR+XDN is a lot more profitable than merged mining with FCN.

So with that in mind, does anyone have particular experiences or opinions with either XDN or FCN? Which one seems like a more promising coin to mine or invest in regardless of its current value?
