Honestly I'm totally the opposite. I had a very negative impression on k-9 when I tried to use it a long time ago because of it's old interface. However I recently needed an email app, I tried Fairmail but it has so many options, and its UI is very weird. I switched to K-9 and its perfect!, yes its not fully modern looking but its easy to use and simple to get started with. If K-9 stayed with the holo UI I probably wouldn't have used it.
