DigitalNote (XDN) vs FantomCoin (FCN)?

I recently just got back into mining a couple months ago and I decided mine with Minergate (yes I've read all the stories, I'm willing to take the risk). The Minergate software has an option to do merged mining with Monero+FCN or Monero+XDN. The smart mining option on Minergate which is supposed to select the currencies with the best trade values to make you the most money always selects XMR+FCN for me, however it seems like the value of FantomCoin is a lot worse than DigitalNote. Because XDN's difficulty is a lot lower than FCN, I can mine a lot more XDN and so far it's been making me more money than FCN.

I'm wondering why Minergate's smart mining keeps pushing me towards FCN though? Am I somehow mistaken that XDN is better than FCN and that I should trust smart mining and go back to FCN?
