Oddly, you didn't gain any space by going from 5" to 5.5" since the iPhone 6 Plus only has a 1080p screen. (Statistically, that's what you likely had on the Android phone since most 5" Android phones have 1080p displays). I'd be curious if you find a 5.5" 1080p screen more productive than a 5" 1080p screen. I'm using a 5" 1080p screen now and upgrading to a 2,560 x 1,440 6" display (Nexus 6) primarily for better web browsing on the go.
