I would say Android. Apple really disapointed me with the latest iPad 2. There's nothing new and innovative here.
Honeycomb has a superb notification system compared to iOS' stupid full screen block. You have a real tablet optimised desktop with widgets and multiple homescreens, a true useful web browsing with Flash and tabs, real multitasking and everything is optimised for a tablet to be productive but simple.
You really feel you have power and control of what you are doing and can do, you should take a look at some Honeycombs video.
