I would think the Taycan is just a slimmed-down, more sporty Panamera. Finally, the basic price is cheaper. For all other brands EV is always more expensive.
The joke I well understood. After I previously had a Panamera I find that you can not put both on the same level. Porsche makes a difference with more luxury in the Panamera. Self-closing doors that are held in every position. I miss it very much.
