I upgraded from an S7E to the Note 7 for one important reason: memory. The S7E has 32gb, the Note 7 has 64gb. By the time I load up apps and Oculus Gear VR stuff, my S7E was getting very low on free space. The SD card is an incomplete solution - many apps can't be moved off primary storage.
I find the Note 7 and S7E to be nearly identical in terms of use and convenience. There are a few niceties on the Note 7 but nothing I can't live without (except the extra memory.)
TMo is shipping me a loaner S7E until the new Note 7's become available at which point I'll swap (again). I'm getting to be an expert at migrating my apps, settings, and data from one device to the other
