Interesting. Because I have a much harder time typing on my Pixel. In fact, I hate it. I wish I had a blackberry.
When I use iOS devices, it feels better but I don't use them enough to have used them in anger. Ok, well, yes they have made me angry but for other reasons than the keyboard hence why I'm on Android lol.
I used a Clicks keyboard with a folded Moto Razr for a while and it was Blackberry-esque. The keyboard is a little narrow compared to the Blackberries of yore, though. I'm somewhat hopeful about the Clicks Communicator which is wider, but sadly still only a four row keyboard.

To be clear, I only kind of recommend the keyboard. I stopped using mine after a while because of how awkward it was with the Razr unfolded and never actually found it faster or more accurate than the on screen keyboard.
