Yes, I have a Torsen in the front to match the Torsen in the rear. They operate the same as a Truetrac. I have a Truetrac on a 69 Fairlane Cobra and can assure they have the same characteristics. For the most part you don't know they are there. They just give you better traction compared to an open axle.
If you want to get nit picky, there are a couple minor things a Torsen does on the front that may let you know it is there. I find on a cold morning, the steering is a little "sticky" on center when starting to turn (this is in 2WD). This goes away after a few miles when the front differential starts to get warmed up. Most people say they don't notice it but being an amateur sports car racer for 30 years I notice little things like that. Also, when in 4WD the steering wheel tries to pull back to center when you are turning while accelerating. It doesn't do it if you are coasting or not putting power to the accelerator pedal. The harder you accelerate the more the steering tries to center. This is more noticeable in higher traction situations like wet pavement. It is near unnoticeable off-road. With power steering it is not difficult to overcome but it can catch you by surprise if you don't know about it.
The only thing in the rear they do that may be considered a slight negative is; when taking out from a stop and turning a corner, it is very easy to get the inside tire to screech a little if you put a little too much power down. This also happens when you are gong around a sharp corner and want to accelerate. It doesn't totally break loose and loose control, it just makes a little screech. It is something I got used to and just learn to modulate the accelerator pedal. Again, this is something many people say they don't notice.
I can tell you the positive benefits of having the Torsen or Truetrac (front and/or rear) very much out weighs the minor little quirks you may or may not experience.
