I play on both sites pretty consistently and I vary between the $3-4 GPPs and the $20-33 GPPs on a nightly basis.
I play cash games on both sides as well mainly $10 & 25 double ups and $1-5 H2H.
But I feel like the more I play I am having more success on DK vs FD. I have been feeling like it is easier to cash on DK, but some have told me that they feel the opposite and its easier to cash on FD.
Thoughts on which one you prefer if you prefer one to another?
