I originally bought Donny's PA800 and gave up on it after 2 weeks. I was frustrated and time trapped. It was special, but the Yamaha 900 OS had me hooked with its simplicity. Gigging daily, I just couldn't find time to spend with it and my songs were in order.
After selling the 800 and playing weeks thereafter with the 900, I started to miss the things mentioned in this thread, especially that 'live' sound.
Like you, I tried Roland and Ketron and found they were not for me - didn't even spark interest. I then decided to seek an 800 again and got my hands on Bernie's.
It took me 4 - 5 months to get the 800 where I needed for live play. I dumped the 900 ages ago now. No looking back because I feel I'm just exploring the endless possibilities.
The 2X is a dream machine - just perfect weight and dimensions. The keybed is great and the extra goodies (vs 800) make it quite the studio setup.
So, that is my story, but by no means is 'mine better than yours'. Just another party that can say good things about a product.
