I'll head them off at the pass . . . there will be people coming to complain about zpool.ca in 3 . . . 2 . . . 1 . . .
I use zpool.ca and get consistent returns. That's all I will say about it. There are plenty of other threads on it, do your own research.
MiningPoolHub seems to be well received and I've seen little complaints about it.
I agree zpool.ca seems far easier to get consistent returns on. I also find that MPH just seems harder to see what you are actually getting for mining performance. Moral of the story is if you want to exchange your own coins don't mine on an auto-exchange pool.
I'd guess part of people's preference to MPH is that it has ethereum that you can exchange directly too, but there are still plenty of delays in getting things exchanged.
