Tracks are still closed, so let's do some bench racing. Might be more productive than arguing which drivetrain's better...
Here's very simple example to start with (have a lot more if there's interest). There's a lot you can see from just a speed trace. And in this case, there's a massive setup change (285 square vs 245/265 tires, same conmpound), so it's pretty obvious even with an uncalibrated driver. Red is the wide tire setup, blue is the narrow, from two days about a year apart. Video below is from the red line, so you can get an idea what the track looks like.
What are the specifics you can spot?
