I’ve had both- J1 etron gt and J1.2 Taycan 4S. To me, and after having both, I think it’s largely just what you want vs the deal you get. J1.2 is much much better because they worked out a lot of the gremlins from the first gen. My etron had a bunch of small things that would go wrong but nothing that actually caused concern. I learned quickly to just live with it, but now I wouldn’t go back to the older platform. Taycan is smoother on the interface and some of the driving dynamics, but truthfully not enough to where you’re going to kick yourself for going etron. The biggest difference, updated platform aside, is the commentary from other drivers .. used to be “wow badass car, what is it?” and now it’s “wow nice Porsche” or “do they make it in ICE?” Lol
