The Galaxy S6 Edge+ and Note 5 are going to launch in a huge number of countries around the world starting next week, despite having been unveiled just a few days ago.
The general take of the Android Police team is that both phones are essentially blown-up Galaxy S6s. The S6 Edge+ is, of course, a giant S6 Edge. The Note 5 is basically an S6 with a stylus. (Oddly, though, both lack the S6's infrared blaster.)
They use the same basic version of TouchWiz, the same basic version of Android, and have very similar styling. They have the same chipset, the same RAM, the same storage, the same cameras, and the same display technology and resolution. They're just bigger.
Of course, with time comes understanding, and no doubt the Note 5 and S6 Edge+ have benefited on the firmware and software front from lessons learned on the S6 and S6 Edge released earlier this year. It's possible they will be more stable, efficient, and well-tuned overall compared to those devices. But that's just speculation - who knows at this point?
With all that said, are you considering a Note 5 or an S6 Edge+? Which one? Neither? As to the why or why not, you know what to do - let's discuss in the comments section.
For me, neither device holds particularly great appeal. If I'm honest, the Moto X Style (aka Moto X Pure Edition (2015) here in the US... ugh) currently has my attention, though that may change come Nexus season this fall.
