which is easier to return lease or financed car?

Leased is generally easier as it's still owned by the finance company. Now there may be fees to pay, and those will be laid out in the contract (early termination).

If you are buying car car, it's technically yours, but you can't sell it until the loan is paid off, which is problematic.

Either "early lease termination" or selling a vehicle which isn't fully paid off can be problematic. And either one will COST you.

When you sell a vehicle back to a dealer (either the one you originally purchased it from or another dealer), you'll only get the actual wholesale value for the vehicle, not the retail that you paid. Also take into consideration that vehicles depreciate very quickly from their dealer selling price. If you owe more than the wholesale value, you'll have to come up with that out of pocket to satisfy the finance company.

Nowadays, getting out of a leased vehicle early is easier than it used to be. Many leasing companies allow for "lease transfers".

In either case, you will probably end up losing money.

Leased seem to be an easy guess.

I mean you were going to return it anyway.

This is a guess.

If you mean stop paying for them, neither is easy and they will pursue you for the deficiency on the contract.
