Siri and Apple Maps certainly come to mind.
Regardless in large measure by ICS and certainly in JB, the 'spit and polish' argument is less and less valid. My wife's IP5 feels restrictive where 2 years ago the IP4 felt polished. Things have to keep progressing.
Siri's fine. It might not have everything Google Now has, but Siri still does things like tell me my next calendar appointment when I ask it to. Its far more conversational than Google Now is still. It's advantages and disadvantages.
While Apple Maps isn't great, its worked for me in terms of navigation. If anything Google's latest foul-up with its Maps release is ridiculous too. You lose all the labs features, the offline maps is terrible with little management capabilities. You can't use My Maps that you create on the desktop. Not to mention you can't use My Maps at all on the new GMaps Preview on desktop. No transit navigation, etc. There's a LOT of stuff out there. I can point you to Reddit thread after Reddit thread about it.
In terms of polish, Android is getting there, but at the same time, features are being taken away. People who used to champion Android as the OS offering choice, there's less and less choice. Google keeps taking away features to satisfy the mainstream crowd to make it usable for the average Joe. I can think of countless changes they've made that are considered steps backwards.
On the other hand Apple's only been progressing forward. The one major stumble I'd say is Apple Maps, but IMO everything else has been upgraded along the way. It might not be at the pace you'd like it to be opened up at, but at least there are changes.
I guess the question is would you rather be on the end of possibilities and capabilities opening up or would you like to be on the other end where more and more limitations are being put in place? I don't think Google necessarily needs to place more limitations and restrictions, but the decisions they're making are absolutely boneheaded IMO.
