If you were asking for advice between two similar devices, like 'S6 or iPhone 6' or an HTC etc, well, you might get a genuine 'debate'. However, you're asking, in the cell phone community, the equivalent of someone car shopping asking 'Do I get the Ferrari or the Toyota'. Seriously, there's just absolutely NO comparison! The Note 4 is a 'phablet'...it's huge, larger than the S6, AND has removable battery and memory card. It has the S-pen. It's 10 times what the S6 could possibly be. So, pass on the Toyota and go for the Ferrari.
