I can't notice any difference on the upshift compared to my 991.2 GT3. I thought that the rev-matching was a bit more aggressive on the downshift in the GT3, but I haven't driven the GT4 on track yet. Might be that the engine in the GT3 revs faster and that is the main reason, not the PDK itself. Great gearbox.

No reviewer's mentioned there's a ton of fun to be had between 4k and 7k so you don't have to risk jail every time you go for a drive.

This is when driven in manual mode, correct?

I find no difference in how the PDK works in both cars.......

Interesting....although, night and day different cars and purposes. Being more fun is certainly relative.... and guessing it was primarily due to the manual.

The OP's question was about a GT4 PDK vs 991.1 GT3 PDK. I own a 718 GT4 with 6MT and drove a 991.1 GT3 PDK to compare yesterday as I am in line for a 992 GT3. My impression was that the 991.1 GT3 PDK was underwhelming in Drive as it wanted to get into its higher gears to "save fuel." The car turned into a BEAST in PDK Sport mode, but not necessarily in a "fun" way. Too racy (for me) on the street. I then put the PDK in Manual mode and shifted with the paddles. That (for me) created a great mid point between the Drive and Sport modes. I guess I am just used to picking the gear I want to be in myself. Overall I was reminded how much I love the GT4. My personal preference is for the 6MT, but driven in Manual mode the PDK should still be fun as the GT4 is such a great car to drive. The 991.1 GT3 engine is as amazing as advertised, but the GT4 shines with its great handling, more compact size, compliant suspension and a NA engine that still revs to (only?) 8,000 rpm.

A few good data points showing up; even if I don't respond, I'll be monitoring the input as it comes. Keep 'em coming.

So far, they seem largely positive -> GT4 PDK will behave almost indistinguishably like a GT3 PDK. I especially want to know if anyone notices any greater delay between commanded upshift or downshift and the transmission's response between the two. Doesn't seem to be the case, but I also know that not all DCTs (and tuning) are created equal.

Given my history when I have flappy paddle available, I'll be driving 99.8% of the time in whatever is the most aggressive manual mode. I want fast shifts, shifts that respond immediately to my command (no converting my command into a request that's subject to approval by committee vote before executing; I'm talking directly at the mental gymnastics Tadge used when explaining why the 8l90 was an appropriate transmission for the C7Z... or to my Raptor's 10 speed), and for the reasons detailed by @Dale Allen , I want to command shifts as opposed to driving in auto mode, especially on the street. I'm an old school 3 pedal guy.

Actually Dale hit almost exactly what's going on in my head on all fronts. As I have at least a couple months before lock, although I'm 95% going to do the 718 GT4 if I get the privilege, I'm slightly cross shopping a 991.1 GT3 with the 781 GT4 as, when it's not grenading, I love the 9kRPM GT3 engine, its looks, its PDK, its handling. But I think the GT4 is incredible for the reasons Dale listed. Optimized for a driver's car, mid engined. If only they installed a 9kRPM engine... it'd probably be a 20 year car for me.

In PDK sport mode (718) I would describe it as immediate, explosive, aggressive but not jerky in a way that would cause you to bypass it. The transmission in my Mercedes GLE is jerkier even in comfort mode. SInce discovering the engine runs around 20 degrees cooler in sport I always have it there and no complaints for everyday driving.

Correct!

Looking for vids of GT4 PDKs driven in manual mode where I can see the hands and with a lot of gear changes.

Perfect!

Found the vid I was looking for; reposting it in this thread in case it comes up in a search in the future.

Looks like this car will be a riot with the PDK. If I don't lose the allocation due to stop sale, mine's going to be a PDK car.

And he was driving in automatic mode. Wait until you flick the shift lever and start using the paddle shifters. That's when the real fun begins.

Not for pretty much everything other than the launch control scene. He's slick with the inputs.

And yep, this is what I was looking for.

You're right, was watching on my phone.
