I'm using it and I like it. I like it even better with the recently-released update (comes through their update utility, you don't have to wait for your carrier to do a new firmware).
Used to use SwiftKey, but it doesn't seem to get along with LG's UI all that well. I still use it on my G Pad, since that's got the older LG keyboard, but this new one is very competitive with the best 3rd party keyboards.
