The efficiency of Bitmain's latest miner makes it the only viable alternative to consumers. J/Gh is the metric miners should be judged on when it comes to profitability.
While efficiency is the main factor in profitability, this is a false statement. While the Bitmain S9 is the leader in j/gh it is not the only viable solution. If you are a home miner trying to mine on overpriced power of course your options will be limited.
Other options include the Avalon 7 series as well as a new player on the market ebang who makes the ebit miner. Both are around .13-.14 which is similar to the new Bitmain T9 that is a more reliable replacement for the S9. Do your homework on each machine and you can figure out which one makes the most sense for you.
