I prefer Dogehouse. They have around 18% of the network and have always been perfect for me. Good payouts and never had an issue with downtime.
I like Dogehouse too, but when the hash rate spikes, the web interface goes down until the PPLNS shares are fully calculated and you'll have to wait quite a bit until it's finished before you'll get your coins (even with auto-payout set). For the sake of current dogehouse users, I recommend trying somewhere else
