Better to payoff mortgage via wire transfer or check?

[Kevin Huang]

The lender said they prefer wire transfer in their payoff instructions letter.
They also require the wire to include a bunch of information.
I've never done wire transfer before...is it fairly safe & easy to include everything the lender asked for?

Or should I send in a cashier's check, where I can write the required info on there, and knowning they're there?

TIA
