I uncoiled mine! It's super easy as long as you have a paper trimmer and a hole punch, although the punching part is time-consuming. I just fired up Netflix and went to work. Doing layouts is more of a mess for me than uncoiling was (and getting the wire cutters out of the packaging was ridiculously hard). When it was coiled, my planner quickly got so bulky so quickly I couldn't imagine not uncoiling it.
And I'm sticking with my current planner since it's a Plum Planner bought mid-year (I think it started in June). I'm thinking about changing to Erin Condren after this one ends, although that might mean I'm plannerless for a month. I'll uncoil that one, too, because I love binder-style planners. I was a Filofax devotee for years before I switched to the Plum Planner, and now I have the best of both worlds: a Plum Planner in a Filofax Domino binder.
