You shouldn't be worried about having a board that others have. It's unavoidable unless you get an imported brand. If it's a good board, that's all that matters. If having the same design bothers you, add your own personal flare to it by putting stickers on it.
For board recommendations, here are mine:
Rome Artifact Rocker - Ultimate jib board. It is noodly soft and durable.

Ride Crush - A mid flex jib board. Ultra durable thanks to Slimewalls and CleaveEdge. The edges are beefier steel and you can detune the hell out of them. Really cool graphics. Areas become darker when cold so you can see the graphics pop out.

If you can afford it, my next recommendation is the Never Summer Evo.
