Yeah, I tried using some of the other pools and I keep going back to Dwarfpool.
Why? Because for one they aren't constantly trying to screw you over like a certain collapsing star themed pool, which is what it feels like while mining there btw.
Also, they are one of the most stable, where the front-end is not always under attack. They developed the first stratum proxy for ETH mining to improve connectivity and the pools admin actively responds to questions or criticisms.
I am all for spreading out the hash-rate, but until we get a few more credible pools where the owner is actually looking out for more than a quick buck, I think most people are going to go with the pool where they are getting the most coins for their hash-rate, which is currently Dwarfpool.
