Wish I could be more of a plotter and my aim is to do that as much as I can going forward, but it has definitely been more “pants” to date, followed by “now how on earth does this all come to a satisfactory conclusion?”. I suspect “pants” writing might lead me to more incidental insights and little moments of character enrichment than “plot” – so I suspect the answer might be that I need a bit of both. Perhaps a bit of “pants” writing to start off gives you some interesting characters and scenarios and then one should sit back and get plotting so you don’t have to “kill your darlings” later during brutal self-edit sessions…
