You will enjoy the opportunity to eat a meal and drink some drinks on a plane, without having to produce your credit card.

Otherwise, there's no magic to it.

The seats are nicer, and since you board first, and there's fewer seats per row, you won't have to fight for overhead bin space. If you have a coat, the SD will offer to take it and hang it in a closet for you.

Since you are being 'waited on' more than you would be in Economy, I suggest being friendly and polite to the crew waiting on you. At the same time, if you want a refill, don't be shy about asking for it, just don't snap your fingers or hammer on the call button during turbulence.

You're still sitting in a chair on a plane, it doesn't get there any faster. With early boarding, you will actually spend a bit MORE time on the plane than the guy in 28E.
