The vast majority of people don't notice the turbo lag you say exists. As far as I'm concerned, there is no lag in my 12C. I doubt there is in a 911 Turbo or a 488.

Since I have a chance to test drive 991.2 Turbo S, 570S and 488 GTB recently I can tell you that turbo lag is the real thing. 

Biggest turbo lag is on 570S. But, I love that car. 

991.2 Turbo S has smaller turbo lag. It is still there although. 

488 GTB... You had to drive one to truly get the picture how good this car is. The best possible throttle response for a turbo engine. Fast as possible, confidence inspiring handling, amazing traction. Should I go on?

It is IMO the best sportscar currently on the market. Second is IMO 991.1 GT3. Third place is shared between 570S and R8 V10 Plus.
