Was looking for similar boards over here, you might find other interesting options http://www.snowboardingforum.com/boa...ide-board.html
I just comment on the boards I or the husband did ride.
I own a Flagship and absolutely love it for steep n deep. It's super stable and responsive. Also a great aggressive board for charging/carving morning groomers. The only draw back is its rather harsh ride in afternoon crud. It's not an all day board. Navigating it through a mogul run can be exhausting. However, in good conditions, it's fun, never ridden a board I felt so confident to ride fast.
I've ridden the NS Raptor as well. Compared to the Flagship it is soft. Its also chatter free, great to carve, and compared to the Flagship it handles crud nicely. More on the all-day side. But I couldn't accustom to the rocker. The wobbly feel while straight lining is not my thing. Others have no problems with that, husband owns that board and bombs runs confidently. However, he thinks of getting a Flagship as well since he also loved its stable locked in ride and wants to make the Raptor his afternoon crud board. So if you consider a NS, check first, if you like how rocker ride.
Don't know the Landlord, but checked it at the shop (where the guys actually know the boards they sell) and was in that turn recommended a Volkl Selecta. Hubby did demo that Selecta and liked it. Comparable nimble smooth ride as the Raptor, so if you don't want to go for a rocker and don't want a plank, the Selecta with its camrock (mini camber) profile could be an option.
Hubby also did demo the Rossi XV. Obviously stable and fast and great in pow. But the insane magtrack is needless for the rather soft snow we usually ride (we don't have icy groomers).
