The MFT has been pretty decent in my Focus. There are a few glitches now and then but I know how to work around them. On scale of 1-10 I'd give it an 8 in it's current state. I'd rather have it than not.
The DCT can be both a blessing and a curse. As others have mentioned, it's fine when the car is moving faster than 20-25 MPH but a bit lethargic around town or any type of stop and go traffic. Forget about accelerating quickly from a slow roll, it doesn't respond very well at low speed most of the time. Sport shift mode is the way to go in these situations.
With that said, I really really love this car and still wouldn't trade it for anything else in this class. Maybe another Focus with the 5MT but I am on the fence about that because I'd rather have an auto.
I think Ford will get things ironed out, but it will take more than software updates to correct the low speed issues with the DCT.
