Fuji's JPEG colors are great, and if you're willing to spend the time to get it right in the camera they are sufficient for personal work. Especially if your personal interests are being out shooting instead of sitting behind a computer editing.
I mostly agree but I find modern software algorithms with "automatic" adjustment on the RAW tend to do a good job for the stuff I'm happy to have a lower quality JPEG anyway. It allows me to spend less time adjusting settings on my Camera, just load it into lightroom, auto-wb and auto-color tone and the jpg is "ready" to send.
I do almost no editing beyond crops and occasional WB / color correction, but holy crap you're leaving SO MUCH on the table by marrying JPEG on the camera.
