I love EyeEm interface. Fhotoroom is too android-y to say the least and a little heavy looking.
However, connecting to other social networks is a nightmare on eyeem!
I like EyeEm interface too but the filters are just horrible in my opinion, even tho I hardly use them and mostly upload clean photos (mostly nature shots etc, check my profile). I guess I could use EyeEm primarily and just use Fhotoroom to edit the pictures, that could actually work
