I have a Galaxy Nexus and just loaded Jelly Bean on it. I used to own an iPhone 4. The iPhone definitely has a high level of polish, but Android is closing in. Jelly Bean goes a long way towards that. It is very responsive and snappy. I also own a Sony xPeria Play for handheld gaming and it runs most things pretty well, including an Amiga emulator! So I feel that Android has made great strides in the last several years and keeps getting better and better.
