I have a DFGT as well and prior to that I was using a MS wheel on the 360. I was quite impressed with the FFB of the DFGT at first. I then got a Fanatec Turbo S and used it for a while. I went back to the DFGT and would have swore the FFB was down to 50% or less but it was at 100% just felt weak after the Turbo S. I then got a Fanatec Elite and used that for almost a year when I started getting a odd electronic squeal from the radio when connected to the 360. I set up the Turbo S and ran a race. The first corner I hit I thought the FFB must be set lower on this wheel because it felt so soft so I looked at the settings and it was set higher than what I use on the Elite about 20% higher but felt about 20% weaker.
It is fun to watch the look on my friends face the first time they try to turn the wheel which is almost always before the car starts to move and even at 50% there is a lot of resistance on the wheel in that state. Some of them will reach over from the side with one hand and try to turn it then have to add another hand
