Yes you are weird, if "weird" means exceptional and unique.
I usually have two lines as well, most recently having one line on AT&T and one on Sprint. I just canceled my Sprint line, however, because their network just plain sucks in my area and the unlimited data plan means nothing if you can't even get better than 3G speeds.
As for having multiple phones, I have at least two phones at all times. I too jump back and forth between iOS and Android as my daily driver. I used the iPhone 6 Plus from September of last year up until a couple months ago. Now I'm using the S6 Edge+ on AT&T as my daily driver. I still have the iPhone and a Nexus 6. Neither of them are on a line of service, but I still play around with them on WiFi.
I'm not sure why you got both the Note 5 and Edge+ since they are basically the same phone and neither of them runs iOS. I will probably get the new Nexus when it comes out later this year, but I can't imagine it replacing the Edge+ as my daily driver. The camera and screen are so spectacular on the Edge+ that I'll probably be using it through the new year.
