The best pool is the pool that makes you happiest. If having peace of mind is important then mine on the most stable pools like BTC Guild or Bitminter. If guaranteed income makes you happy look for a PPS pool if it exists to negate variance. If you like gambling and the thrill of possibly making double earnings mine on a smaller pool.
If Ghash.io wasn't trying to take over the network they would be an option, but in their current state they need to be avoided at all cost.
IMO P2pool mining is better for him as he has good hash rate. But where did 6TH/s miner came? I couldn't see any on internet which is alrady made but I found one which is under development.

Spondoolies Tech SP30 is the only legitimate 6THs miner known to be in the pipeline. All others (you know who!) are scams until proven otherwise.
Thanks for the site and details. It is September batch. The miner looks great and it isn't using much electricity, right? I hope nobody falls into any type of scams.
