With the Martin TRG and my own, I have noticed an improvement in the draw cycle, most notably near the end as the draw force curve drops into the valley before coming up against the hard stop/wall. Both TRG types helped make the "hump" into the valley less pronounced. That's the biggest difference I've experienced. It's been long enough time since I had a straight guide rod and slide installed that I don't recall if there was much else different in the first part of the draw cycle between the two systems. Since both systems pull the cables very close to the same amount to the side at the first part of the draw cycle, logic would seem to indicate the "feel" would be very similar during this phase with both straight rod and TRG.
