Help with womens board

Hi I'm new here. I'm buying a new board, and I was wondering if there was a big difference between mens and womens snowboards. The last board I bought was a burton jussi 154, about 5 or 6 years ago. I am looking to buy a new board this year and am trying to decide between the Rome blue 151, Rome lo fi, NS infinity not really sure.
The board that I've been riding is IMO a bit too big and stiff for me. I like mostly downhill riding because that's what my friends can do, but like to spend time in the park once in a while. I ride mostly hills with man made snow, but do a yearly trip to big mountains. I am 5'5" 130lbs and have size 9 womens boot. Any suggestions would be very helpful. I haven't paid much attention to new boards and companies, and only chose my last board because of graphics. (Big mistake)

Not sure if it matters, I've only ridden mens boards, my previous one was 151.
