Well, it's only a few seconds difference, but yes, in general (when Lightning payments don't fail, which is often if it's a modest amount and one is not connected to a large centralized node) the lighting payment flow is faster and more polished.

Because of the way Monero works (decoy outputs have to be fetched from the node your wallet is connected to and then sent to the client), this will probably always be so.

It depends on what you're optimizing for. I'm willing to wait 3-5 more seconds and enjoy superior privacy.

Where Lightning has the indisputable upper hand is if you need to make multiple small payments in succession - assuming no routing problems, this will be very fast (whereas the 3-5 seconds per tx on Monero will quickly add up).

Furthermore and to finish, change outputs get locked for ~20m in Monero, and usually users don't have many utxos available for quick spending in succession for this reason.
