The Model 3's suspension was revised a couple years ago, and enthusiasts seem to have stopped complaining. Both cars are within a few seconds on the Nürburgring (7:42-7:44ish), and the Model 3 Performance is faster on Laguna Seca. Both cars need better brakes if you're going to flog them around a track for long periods of time, but that's a pretty common issue with performance versions of sedan/SUV EVs.
Hard pass.
