The Taycan looks like a great performance car. It handles better and that is the essence of a sports car to me. That said, I'd rather have my 3 year old Model S. Why? Because the Taycan wouldn't work as a daily driver. The lower ground clearance of the Taycan means I'd be scraping the bottom too often, while the S is high enough for normal use, plus I can raise it with air suspension. The S has much more interior space, plenty of room for the kids and luggage. Even my 3 year old S has better range than the Taycan (269 miles EPA), and the supercharger network let's me go just about anywhere without concern over charging. Tesla service has been stellar. Every Tesla service center (and ranger) can service a Model S, whereas Porsche will likely have to have an EV specialist "available", as has been the case for GM, Jaguar, and Audi.
Don't underestimate this last aspect. I'm constantly amazed when people ask me "how I like my Tesla", they often follow with their own plans to buy one. When I add that other EVs are available from established automakers, their response is often that they don't trust EVs from the others, but have confidence in Tesla. I was surprised at first because this is coming from older people who I assumed would put more trust in the old guard. However, I get this response repeatedly and more frequently as Tesla grows.
