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

I have nothing bad to say about Multipool. They went down this morning on me for the first time in weeks. Going through all the threads I see more people complain about Doghouse though. Multipool is back mining DOGE again and dropped that accursed MOON now.
