I'm closing this, just like other similar threads, as we don't allow comparison threads.
We don't allow these threads as it can very easily lead to heated debates/arguments about which phone is the "best". It's also an open opportunity for fanboy trolls to come along and ruin such threads.
Also, asking in the M8 forum will undoubtedly bring bias results as most people in this section either have the M8 or are getting the M8.
If you wish to ask such a question, please use the existing Device Suggestion Thread
