Yep, I find it better to "slide" the text instead of tapping every single letter. It's faster for sure.
You can easily switch between two languages (primary and secondary languages), you can add or remove words to the language dictionary as well as you can define shortcuts for words or short phrases.
And you can easily switch between sliding and tapping mode.
