Those who have used iOS, BB, WP phones - how do you rate and compare their native keyboards to android?

Personally I find the android stock keyboard to be pretty terrible. It'll correct small words to other words that make no sense (eg. typing "put" and it corrects to "out") in context. It also has no recognition of when I accidentally press "b" instead of 'space', so something like "suddenlybwent" confounds it.

From when I had a Lumia, the keyboard was the best thing on it - excellent prediction and correction.

Same for Blackberry's current touchscreen whatever it is phone - it knows what you meant to type, and doesn't swap words you don't want swapped.
