From the units I have seen and heard of the Marvin Ultimate L&S is a very nice unit (Marvin generally does things right when they release them). As far as Fleetwood, mixed opinions and from what I recall only available in all aluminum (no wood).

You can see the features on the website. One feature that stands out is the flush handle. Most others have a handle that protrudes and is removable so the door can go into the pocket.
