Should I buy spring/ park skis or all mountain/powder skis?

I’m getting late in my first season of skiing after switching from snowboarding. I’m ready to get my own set instead of using season rentals. I’m wondering if I should pull the trigger on my all mountain skis (probably m free 108s) or get some fun park/ spring time skis. Any advice on this? I have a demo credit I need to use either way.
