I'm sort of in the same boat as logik brooklyn above. I was looking to upgrade to an iphone 6, but there were/are none in my area. The only ones I could find were the 128GB versions which I was not about to buy.
One of my coworkers showed me his note 4 and was telling me all the cool stuff it could do. I was pretty blown away by all the stuff he was rattling off. Will I use all of the features? Probably not. But it's cool having them.
In short, I left apple and went with the note because of inventory limitations in my area.
I'm staying with the note because:
Stylus and drawing apps - I really like to draw and doodle. Having the S-Pen and s-note and sketchbook is really cool and fun.
Camera - I make my living as a video producer so the camera in my new phone was very important. The Note 4 totally delivers! The difference between the 6+ and the note 4 are very minute differences to me. I've been pretty happy with the camera.
Screen Size - I didn't plan on upgrading to a huge screen. I went from an iphone 5 to the note 4. At first, I thought the note 4 may turn out to be too big for my liking. But now I'm totally sold. I love the screen space, I love the size of the phone and when I pick up an iphone 4-5s I immediately wonder how I didn't ruin my eyes having to look at all that small text/pictures.
Apps - android gives me all the same apps (outside of apple's own apps, itunes, imessage, etc.) I need to maintain my productivity level.
Storage space - as mentioned many times before, the note lets you add more storage space if you feel the need
Removable battery - I may never take advantage of the removable battery, but I like knowing that if my battery dies, my phone is not necessarily dead.
