I LOVE the Swype keyboard!! It literally was the first app I installed as soon as iOS 8 was completed on my 5C. I don't use voice dictation in the messaging or email apps, so the fact that feature isn't avail in the Swype keyboard does not bother me
I've tried Flesky and Swiftkey but I reverted back to Swype right away. It's a feature my son has on his galaxy S4 that I was ALWAYS a tad jelly of, LOL. But I'm happy to finally have it!! ☺
On my Air I have the dark keyboard set and on my 5C I have the sand one.
I'm totally enjoying iOS 8 so far as well☺
