The Jaguar does have advantages. The Matrix headlamps are awesome, it has a heads up display, the interior _is_ nicer, and IMO, it looks like the ant's pants!
However, the Tesla is faster (at least the Model S), and the P100D of either the X or S blows it out of the water. The Model S has a longer range, more space in the back, both for passengers and luggage. The X has _even more_ space, and the Tesla has a nicer screen, with better software. The adaptive cruise, and lane keeping features also work better IMO.
However the three big winning points for the Tesla: 1. Charge time: The Tesla can just charge faster, and it uses a lot less energy per km (or mile), so you end up needing to charge it less often, and when you do charge it, it can charge faster. 2. OTA software and map updates. This is just an awesome feature, particularly the map updates! They are just pushed to your car, no need to get it serviced to get the new maps, which also means that your maps tend to be more up to date. 3. This one is probably temporary, but still important for now: The Charging Network. The Tesla superchargers are in a lot more places than CCS-2 100kW chargers, which makes the Tesla more convenient for longer road trips.
If you _never_ do long trips, then 1 and 3 won't make any difference to you, since they both have enough energy for most people for day to day running, particularly if you have a charging pole at your work and/or home.
So, as I said, it's not clear cut which is better, since different needs could tip the above scales different ways. Which is just great IMO, since real competition is the only way forward.
