As a registered Swype user, you can now not only get the vanilla Swype on Samsung, but also the latest Swype beta. I never used beta products with Swype being the only exception.
SwiftKey has now also brought out a "continuous" drawing equivalent capture method, but as Jim states, Swype is ahead of the pack, with regards to Swyping using the drawing technique at least.
SwiftKey has the advantage on the dictionary side allowing multiple languages, which is handy for us bilingual folk.
With the world record in speed texting has been held by both Swype and Swiftkey.
My sense is this year Swiftkey's Continuous texting will mature, but until then though both are installed, Swype remains my preferred Android keyboard.
