They're comparable if your ownership window is 3-4 years and you never need to drive very far.
But leasing new cars is a VERY expensive way to own vehicles - you're essentially taking the max depreciation hit over and over. You're much better off financially to buy a car that's hit the lower slope of the depreciation curve (4-5 years) and using the money you save on preventative maintenance - and keeping the car at least 10 years. Except for my old truck, that's how I buy all of my cars. I drive (er, my wife drives) pretty nice vehicles.
And even when something catastrophic happens I'm ahead. When my RRS had the timing tensioner issue that affected all of the 2012-2015 5.0's, it cost me $5500. Car's paid for...that $5500 is about a year of lease payments on a Model 3 and less than 4 months for a Model S. That happened 3 years ago and, besides a suspension compressor that I replaced myself under warranty, I've had zero issues with that truck. And I'll own that car long after the battery is toast on a Tesla.
