Depends on lots of factors.
Technology is changing rapidly. Do you want to keep up, or are you OK with the current level for a while? I bought a cutting edge cell phone and owned it for more than a decade. This was an amusing experience, as the phone gradually went from "Wow, that's cool" to "Wow, that still works?", with a long period of "boring phone" in the middle.
Price including tax rebates. I've seen some crazy cheap leases in the past, one in 2015 that was the cheapest I've ever seen a Leaf, but the leases I've seen for the 2018 are much more expensive. However, the lease still might be better if you don't have enough owed in taxes to take advantage of the Federal non-refundable credit. Don't forget the impact of sales taxes. Businesses have tax reasons to lease.
Where you live and how much you drive in a year. Cooler climates are better than hot climates for battery life, salt on roads rusts out any car, leases have mileage limits.
Look at the extra cost to lease, and ask if it is worth it. If the extra cost is zero or even negative, then there is little reason not to lease. If the extra cost is a large enough fraction of the car's price, then there is little reason not to buy. Between? Harder to say, of course.
