I will also cast my vote for Vanillacoin. I have done some research and it is the one I am currently mining and investing in to start. It has also seen a recent uptick in price so I have actually been able to cash some out and convert into BTC to help offset some of my mining costs. I plan to keep about a 50/50 balance of what I mine and keep for now. I haven't had the coins long enough to check out the staking aspect yet, but looking forward to seeing that appear in my wallet one day.
