I've been testing the third party keyboards. In fact, I'm writing this response via the Swype keyboard on myth iPad. I haven't tried SwiftKey due to possible privacy issues.
While the Swype keyboard had the cool factor, and I'm sure I'll get better with it over time. I don't see that the third party keyboard are more effective than the iOS 8 keyboard once it learns your nature of typing.
I understand the third party keyboards were big on Android because some of the stock keyboards were terrible, but are these third party keyboard that much of an advantage on iOS 8?
Swype could be great for a very quick reply, but I don't set that it's extremely effective for more than that.
What say you?
Are third party keyboards just another one of the "awesome features"'Apple fanboys had to live without?
