Lol yeah, I've been on quite a few phones since the S3: HTC m7 -> Nexus 5 -> Nokia Lumia Windows Phone (this got returned within 2 days lol!) -> Galaxy S5 -> LG G3 and now on the Nexus 6. I'm loving the 6, I swore I'd never get a phablet, but here I am and I'm loving it! Mostly loving pure android and the ability to flash away without insane hacks to get around locked bootloaders.
I phone hopped for awhile too. Happy on all of them, just REALLY impressed with this one so far. I went from the S3 to the S4, Nexus 5, Find 7, Moto X, Moto G and G3. Grabbed this N6 on launch day. One of the lucky few.
