I have a Forum Bully & really like it. I've only gotten about 5-6 days on it last season, but it definitely made for a much better riding experience than my stiff camber board I was riding the 2 seasons prior.
I'm about 90-95% groomers & 5-10% park. It's basically a Youngblood with a slightly setback stance, so it can still handle all the park you want to throw at it while staying a directional twin with a slightly stiffer tail (good for ollies/jumps).
I haven't ridden the other boards listed, so I can't help you out there. I did look at some of the LibTech & Gnu boards too, but I couldn't pass up the deal I got on my board.
