I'm 5'6 + 165lbs so I'm almost identical height/weight as you. I've been riding a 150 GNU Park Pickle for about 2 years, which is again very similar to your 147 box scratcher.
If strictly jibbing in the park, I feel that my pickle is like magic. It's easy to spin on and off features, super fun doing ground tricks, and is pretty decent at fast speeds and even powder's not that bad. But carving felt really weird with this board. I didn't really have anything to compare with at the time but I cannot get the deep aggressive turns or ride as fast as my friends, so I thought that maybe the short length, magne traction side cut, and reverse camber profile all had something to do with it.
Later I got a 154cm Capita Defenders of Awesome, it's a full camber board with rockered nose/tail just so that it can stay afloat better in powder. Let me just give you my experience for reference (because I don't know your riding style and my experience might not apply to you)... But for me, switching to this board was absolutely better in every single way possible. It only took slightly more effort for tricks but it's just something I quickly got used to. I felt really happy with the increase in board size which sacrificed an almost unnoticeable amount of effort to initiate tricks but gave me much better ollie power and stability off bigger kickers. I didn't feel any difference pressing or spinning onto features to be honest after I got used to the board's new length and stiffness.
Then in terms of the freeriding/all mountain portion the upgrade was way better as well. I can hold much more aggressive carves on groomers, riding fast felt stable, and again... ollie or popping with this board was like twice as powerful as the shorter pickle.
Ground tricks though was slightly different. On the pickle I can basically press infinitely with combinations of 180s or 360s with almost no effort. On the 154 DOA I need to really make sure I have the right movements or the board will want to stay on the ground. However, all my tricks felt more stylish and more clean when I'm using the 154 DOA. The best comparison I can think of is if you youtube Ryan Knapton vs some Japanese "Ground Tricks Masters". Equally fun.
If you ride similar to me then I really recommend you trying out a 152 or 154 board and see the difference. I felt like a shorter board helped when I first started to learn jibbing but a longer and stiffer board is much better after a while.
