I don't think that is a fair comparison. The Cake is 10 000 $ more then the Sur Ron.
Its like asking if people would choose the Nissan Leaf or Tesla Model S. They both do their job just fine, one is a large 7 seater with performance like a sports car and range that makes it only naturally to take a brake after 6-7 hours behind the wheel. The other is a small urban car with low range and performance but costs 1/3 of the Tesla.
