Worth upgrading from Note 3 to Note 4 for $250?

[Slappy_G]

I found a friend selling a Note 4 in really good condition for under $250. Are there any reasons I would not want to move to a Note 4? Especially looking forward to the OIS on the camera and the full support of NFC for Android Pay (yes, I know Samsung Pay is Note 5 and up only).

Any issues you guys would see that would make that a bad thing?

Why?
Removable battery and SD Card or anything else?

All other specs remains same? I'm in lookout for something similar to Note 3 but more powerful (CPU and RAM), more and removable battery, more and add more memory, more screen but yet to find one.
