My take (very subjective):
ROME Jett: Eh. You'll be happier on the Rome Vinyl. It'll grow with you.
K2 Lunatique or Moment: The moment is made with park beginners in mind. It would be pretty unstable on the rest of the mountain. The Lunatique is a very popular board for progressing riders and would be a great choice for you.
NITRO Mystique: Don't know much about Nitro, but this looks like a good option
RIDE... i got kinda confused... lol
CAPITA: Space Metal Fantasy is a very soft, fun, popular board. Stable enough for all-mountain riding.
BURTON feather or lux v-rocker: Stay away from the Feather. It is overpriced and you're likely to outgrow it quickly, especially if you ride often. The Lux is a better option. Also consider the Lipstick.
"Easier" boards are softer and easier to flex. They aren't as responsive so you can make mistakes and not eat it as a result. Reverse camber boards are more forgiving because it's harder to catch an edge with them.
Tell the board shop your size, your level of experience, and your interests. Have a few boards in mind. Know what questions to ask.
