I think you'll be very happy with the new addition. I've had the Forté AP for a few years now and it has been super reliable, very consistent, and has needed only the occasional cleaning.
So you know if you can get a single dose hopper for the Sette? That's one accessory I got for the Forté and I seriously love. I use the lid as a cup for measuring beans, it pours into the hopper without dropping a single bean, and it's large enough to hold beans even for a larger chemex setup.
