What's your experience of owning both an android/iOS device at once?

I've been interested in the Nexus 7 for a while (now the 10) and I've always loved using Google/Apple's stuff. I currently have an iPhone 5 ,used an iPad 2 (gave it to my dad), and have always been with iOS for several years, but I'm open to try Android and don't wanna make a full switch. To those who own both devices currently or not, how's the experience of having the best of both worlds?
