I'm with everyone who enjoyed the WP keyboard. As for the Key 2, I had a chance to hold one in my hands this morning and while the bigger keyboard felt a little nicer, the overall change from the Key 1 isn't worth $250 in any way, shape or form. I thought the extra RAM and the newer CPU would make it noticeably quicker, it doesn't. It still has kinetic scrolling stutters and some delay when tapping icons. I grabbed a Key 1 instead. It's working better with the Gear S3 than with my S8+. For some reason, the Galaxy was having Apple Watch tendencies in that notifications were being silenced on the phone?!*#
I'd really suggest you do a prolonged hands-on with the Key 2 if you're seriously thinking about it.
